I've got a cheap 4x6 Clarke bandsaw and I'm needing a new blade. What blades do you all recommend for speed of cut? Longevity is second to cut speed. I love being able to set up the saw and turn it on and go work on something else but my current blade is so slow that I've just been using the plasma cutter which ends up with about as much time grinding a smooth edge. I'm still not very good making straight cuts with the plasma.
