Matt,
Starrrett, Morse and Lennox are the three USA made blades you want to chose from.. You want Bimetal, I run them slower and I keep an old candle or piece of canning Parafin wax to dress the blade some just to keep it cool. i think it helps cut down on chatter. Also when you put on a new blade. Don't go full pressure on it on your first cuts There is a little bit of a break in time and you will get more life out of the blade that way.
