I think you know what I use? My $5 grinder from Menards.
They have sales where if you can get it in a bag, it's 50% off or something? I'm sure I paid $5 for it.
I just use the dewalt wheels and it works great.
I had looked at the cut-off saws, but since you always cut a little long any way, the grinder works perfect.
Did you get my e-mail on the DVD updates?
