Mickey:
Welcome to the discussion group. A few differences in these two saws. First and foremost the TS2424 is a cast iron table saw, while the BT3000 is die-cast aluminum. The table surface is significantly bigger with the TS2424 and the fence is much heavier. The BT3000 is a good saw and it has many supporters, but if you talk to many woodworkers you'll find that they will recommend a cast iron stationary unit over a smaller aluminum unit.
This is just a quick summary; there are many more differences in these two saws. If you have any more questions post them here or you can e-mail me at
