I have the $199 Delta model. For what I used it for it was fine. But if you plan on running any amount of Board feet through it, I'd go with an upgraded model. I hear good things about the Dewalt. 735 , I think is the model number? About $450ish. I also read you really need the wings you can buy for it though. Several people on this site have that model and can provide better feedback on that Dewalt.
Far as the delta, if you use it sparingly, it will do the job. If you want to run long boards, and lots of them, go with something else with more beef between the buns.
