Hi Lee, It depends on what sort of woodworking you're going to be doing. If you look at the higher end of the Table Saw market, you'll note that the rip fences lock in on both ends of the table. The cheaper table saws don't. I doubt if you can do accurate rip cuts on longer pieces of stock on these cheaper table saws. If you're just going to be doing outdoor furniture or small projects that don't need very accurate cuts, I guess you could get away with using the cheaper table saws. The first table saw I owned was a RYOBI. I ended up returning it and getting my money back. I went out and bought a BOSCH GTS 10 J. It's not really a "higher end" table saw, but what a difference! Totally happy with it.
Cheers. - Charlie
