BUY! (It's fun to spend other people's money)
I have the exact same model, which I bought barely used, AMERICAN MADE, for $200, AND I got a mobile base for it. So far with a sharp new blade, I've never taxed the 3/4 HP motor. It works just fine. I bought it because these saws are like a Chevy 350, you can buy many upgradable/aftermarket parts and have a high performance saw for the fraction of the price of a ferrari.
You will not regret it. Last year there were guys here buying the last of the american made ones, minus the stand and motor. I think they were still paying about $400 for just the frame...
