<font color="blue"> OkeeDon . . . I don't have a SLIDING compound miter saw . . . Hmmm!

(Laughing) Well, I cheated. I already have a very good quality compound miter saw, and my son-in-law has a nice Ryobi cordless miter saw I can use, and I have a 14" chop saw. But, I need to cut a lot of 8" wide material, and I decided it would be faster with a sliding saw than a handheld skil saw. Harbor Freight has a current online sale on a Chicago 10" sliding compound miter saw for $99.99 (normally $199.99). I went down to the local HF store with a print-screen of the online sale price, and they honored it. I don't normally buy extended warranties, but apparently when an item is on sale, HF also cuts the price of the warranty. So, I got an additional 24 months (27 total) of no-questions-asked replacement for $20. I should be mostly done with my cutting projects by then, so I considered it $120 well spent.
A brief review -- it works, but the entire head and support is on dual sliding tubes mounted low, and the bearings are not very good. In other words, it feels rough when sliding, and occasionally hangs up, requiring an extra back and forth "bump" to complete the slide. Still. it produces a much straighter cut, much faster, than a skil saw, and I eliminated the need to use a speed square to draw a continuous line, because I can use a single pencil dot on the board to line up the saw blade. When you're making a lot of cuts, such a simple reduction in is nice.
When I got to the HF store, they also had an in-store sale on a 12" sliding compound miter saw, also a Chicago, but much higher quality, with a single large tube on which the head slid smoothly. Normal price $249.99; sale price $199.99. After some thought and some consultation with the refreshingly candid store manager, I decided to go for the better saw -- but they were out of stock, and I had a need for it that day. Upon reflection, I decided that there is better availability of a greater variety of 10" blades, and the 10" saw would do my job with no complications, so I saved a hundred bucks and sprung for the cheaper one.
I used the saw quite a bit yesterday. I added some lithium grease to the sliding tubes, and had no problems. I'm actually cutting hardi plank (7-1/4" wide), which is notoriously hard on saws, so I'm glad I got the warranty (the dust gets to motor bearings).
Best $127 (including tax) I've spent in a while...
