I too would go with Sears as a source for a non-pro table saw. Almost all saws are nice and precise when running new and with a new (sharp) blade.
The difference is that a professional model like a Delta Unisaw will have the same precision after years of daily use--long after portable saws become worn-out.
Buy at Sears and use the money you save to buy a dust extraction system (or a large shop vac and hoses). That mdf dust is just awful!
