I was at the local Lowe's today and had the benchtop sander at 149.99 - 10%. I think ~ $135 for that unit is a pretty good deal, but wanted someone else to add their two sense. Did i make a mistake to pass it up? I can still get it tomorrow if I want. Any input? i want to spend less than $175 if possible. Also Is this a good addition to my shop? I have an occassional need for one, but at the price I thought it was a good deal...
