You can always weld like we did. When we built the Dillingham city dock in Alaska. 90-MPH winds!
See if the smoke hangs around in that kind of wind!Fume Extractors... why so much?

Or maybe run the ducting vertical through the ceiling and then out the side of my attic using a fan like this? I bought one of these for my greenhouse and it works great. Cost is about $150.

The equivalent explosion proof fans start at about $700

- More than 40 over the years. Ten at any one time. Mostly Ford and New Holland
I have Miller's smallest portable fume extractor. It works fine IF the intake can be positioned close to the work.
I bought it "new not in box" for approximately half the regular price, but STILL overpriced in my opinion.
A local welding shop had a job welding some panels at a shopping mall and rented my extractor as part of the requirement of their contract. They said it really wasn't a large enough unit to be efficient but fit well in their work "footprint" and kept the mall management happy.
I was happy as the rental income paid for the machine.
If you're not using a shielding gas, I'd go with Shield Arc's 90MPH winds.
Here's a pic of the Miller mounted on my modded out tool cart.

I was fortunate enough to pick one up from one of those internet auction sites for government agencies for $175.00 a couple of weeks ago. It's not the recirculating type but blows it outside. I still feel pretty lucky.. It's a Nederman brand and looks like it retails new for a couple of grand.

Nice! Do you mind posting the auction site(s) you frequent for stuff like that?

My first post was based on professional opinion after 30 years of HVAC and sheet metal experience even though the welding I did on mostly 12 ga. black iron was on a wood floor in a 100 year old former theater building and our ventilation system consisted of opening the overhead door
For the average Joe, or Dragoneggs, a cross breeze strong enough to keep the fumes out of your face without disturbing the weld and a sidewall exhaust fan to keep the shop clear and bring in fresh air should be sufficient and safe for most projects. A fan with multiple speeds would be nice to regulate how much air is exhausted for different conditions and to keep your shop warm in the winter. I did a job years ago on a large printing press to exhaust corn starch powder they sprayed between freshly printed sheets. They went cheap and installed a standard blower themselves to our hood and duct- it blew up after three days and shut down the press for a week until we rebuilt the whole system again and installed the proper blower...lesson learned!

The biggest reason things like that are so expensive is product liability insurance. I once chatted up a guy who made a nifty little log-tong system that attached to the 3-point hitch, and asked why it was so bloody expensive for such a small amount of steel. He said that well over half the cost was for the liability insurance he had to buy in order to market the things. Too many people do really, really stupid things, then sue when things go badly. Even with the high price, the guy was barely doing better than break-even on his sales.

Yep, insurance!
Our association once considered in going our own private member insurance route so the board of directors had a specialist address us on the procedures.
It involved so much re-insurance and legalities that we opted out, however we did learn a lot.
Way back when a large dept store chain were sued for millions, and lost, because a person decided to use his rotary lawn mower to trim his hedge.
Naturally he lost 8 fingers when he picked up his mower to trim his hedge.
Courts ruled negligence because they neglected to place 'do not put fingers here'.
Today you will notice all sorts of gadgets on a lawnmower and walk behind blowers all designed to make them safer (and more expensive).
Also more maintenance prone.
Our industry was aviation and we could have ended up with liabilities for just about anything anybody had performed on any aircraft before we even touched it ourselves based on negligence on not observing other faults or omissions.
Liability was so bad that major aircraft manufacturers were spending more on liability insurance on some models were actually selling for.
As a result many product lines were dropped up until the gov't enacted some sort of limitations under Clinton regime.
Think about it a bit.
Welding shop and all the fumes, gasses, cutting grinding (silicosis) all of which are generally considered carcinogenic agents with long term disabilities costing fortunes---lawyer's windfall and insurers nightmare.
