The G0715P is pretty new, and I haven't see a magazine review yet. There have been a few reviews on the web that indicate it's a good saw (Lumberjocks, WoodNet). That's not surprising, pretty much all the hybrid saws (cabinet style but < 3 HP) perform well. I have the JET ProShop and like it a lot, and there are several fans here of the Craftsman 22124. The recent test Fine Woodworking did found a winner (Woodtek) but no losers. I saw the predecessor of the Polar Bear Saw (GO478) at the Grizzly showroom when I saw there last year and it looked very solid. The G0715P appears to be very similar, and has a riving knife.
The G0715P runs on 110V, but requires a dedicated 20A outlet. If you don't have 220V available, the G0715P is a pretty good option. If you do have 220V, or would need to run a new circuit anyway...then strongly consider getting the next model up. 2HP is fine for ripping plywood, 3/4" etc., but when I process thicker stock, that's when I wish my saw had just a little extra oomph. Both the G0690 and G1023R are very competitively priced, and when you consider the cost of freight, mobile base, power cord/ plug etc. then the cost difference becomes smaller and smaller. Now, I'm generally a big fan of "upgrading-as-you-go" vs. "buy the last tool you'll ever need", but with the table saw, I'll make an exception. Why? Well, for one, it's heavy, and you don't want to mess with heavy equipment any more than you have to. But most importantly, if you do decide you want something more powerful in the future, it means replacing your Zero Clearance Inserts, crosscut sled, tapering jig, miter sled, outfeed table etc. etc. That's borderline traumatic. In fact, the only reason I bought the ProShop was because two years ago, the only saws with a riving knife were the PM2000 ($2500) and Sawstop ($4000). Had the G1023R or G0690 been available, I would have gone straight for the bigger machine.
So, in short, I think it's a good saw, but if you can spare the extra cash, going for the 3HP means you're not likely to feel the need to upgrade for a loooooong time.
