I need to crimp a new toilet supply on a 1/2" pex line, the old valve was dripping. First, yes, I Hate PEX, worst pipe ever made, but it is what it is. I have already tried a shark bite, and although it seems to grip, it leaks around it, so maybe the crap PEX is out of round? Anyways, I will hopefully never work on anything PEX again, anything new, I always use CPVC/PVC, so I don't want the "best" PEX crimper, but just want a cheap one that works. Any recommendations. Thinking about getting the iCrimp, but figures I'd ask first. Around here, PEX is only used on manufactered homes, anything else is CPVC/PVC

I have one of that style and it works well. No leaks on maybe 30-50 uses.

If you're just doing a small number of crimps I prefer a block-style tool like this:

It works better in tight spots and gives you more latitude to make sure it's aligned properly to avoid spoiling the crimp by getting it crooked. It's a lot slower than a lever arm style but that won't matter for a small job.

I don't understand the PEX hate, I've never had anything but good experience with it.

Me neither. I re-did the plumbing in my house with it maybe 5 years ago and my experience was good too. I did have to pre-assemble a few sections in cramped locations that I couldn't work the crimpers in.
Don't remember what I bought for crimpers...they were in the markdown bin at Lowes...good timing, just when I needed them.

I just much prefer the simplicity of solvent glue PVC and or CPVC. Now, it's been 24 years ago, but when I worked for a plumbing outfit, we did field threaded galvanized gas and air; some roll and some stick copper, and a ton of CPVC. PVC/CPVC is basically idiot proof, every fitting can be found anywhere from a Dollar General to Walmart, and the only issue is, for a homeowner type, every time you need your glue, the dang can has dried up from the last time.

It might be a regional thing? Down here, PEX is generally considered a sub-par material, limited to manufactered homes, although it has snuck into the productionsingle family home market to so degree.

There was another flexible tubing, used for many years in mobile homes, that had problems, but it wasn't PEX.

I don’t know what pex did to get on your bad side but pex is the best water tubing ever made. We can agree to disagree on that. Are you sure you actually have pex not polybutylene? They look similar but aren’t the same product. I usually use expansion pex but I have one of those chinch band pliers that I bought to make some repairs when driving back home wasn’t a feasible option. Since then I’ve made probably 75 connections with it and none of them leaked.

If it was the gray stuff it had the same OD as CPVC and I have glued CPVC couplings directly on it under a sink in my old single wide trailer that I had at the time to add cutoff valves and it was still working leak free about 8 years later when I sold it.

I love using pex. I redid all of the water lines in my house with it. Just don’t use metal fittings if you have well water.

All the water lines in the new housing in this area is PEX. Seems to work great.

That stuff was called Qest. Water lines in my house (34 years old) are all Qest. I've never had a water leak. My understanding is that chlorinated water systems would react with the Qest tubing, making it brittle and to eventually fail. I believe because of this Qest was outlawed as house water line use in the mid-90s. Since I'm on my own well there is no chlorine or any other oxidizing chemical in the water and that's probably why my Qest tubing is still good.

Only problem I've had is that when I want to modify something in my water system, adapters from Qest to PEX or whatever are difficult to find anymore. Local hardware stores haven't carried them for years so I have to find them on line.
