I have a 14" jet, jwbs-14cs i think is the model. I got it for somewhere under $500. It's drawbacks: no tension quick-release, dust collection is a joke, no fence. It's highlights: solid saw, easy guide adjustment (no tools), excellent fit/finish. My adjustments: a $35 tension knob/screw replacement to speed up tension release (5 turns and it's done), still working on dust collection - no viable solutions yet, made my own fence that I can share with my drill press.
I like my saw. I don't love it, I don't intend to keep it forever. It's more than adequate for my needs, and it will probably outlast me. It's a dang fine saw. I do wish I had researched the dust collection issue a little better. I believe newer versions of this same model do much better with a cast-in 4" DC port, mine doesn't have that. If my needs never change, this saw will be mind forever. But I just got hooked on bowl turning ... 6" thick blanks may not be enough for me for very long!!
I have a friend with the powermatic - it has all the whiz-bang gizmos from tension arm, bearing guides, cast-in dust collection port, etc etc. To tell you the truth, I didn't like the ball bearing guides on his saw. To make ANY adjustments, you need two different size allen wrenches, for one. Second, the side bearings are on a cam-style adjuster for blade width. This would be fine except that when you tighten down the "locking screw", it moves the cams, so you have to predict that and account for it before you tighten everything down. Kind of annoying, if you ask me. I also think that ball bearing guides on these smaller sized saws are really kind of a gimick because i saw NO difference in cut quality between this powermatic and my jet - same blades, same stock, etc.
Lots of folks are very happy with their Grizzly. I haven't had the pleasure of using one, yet, but I hear good things. I have an 8" grizzly jointer (g0586) and a friend of mine has a g0490 jointer as well. We're both sold on the quality of these tools. The fit/finish are as good as (or better than) my powermatic or jet tools. I have also heard very good things about their customer service, as well. Never needed 'em, so far, myself!
