If you are looking for a big honkin' belt sander, this is it.  I use this sander two ways:  (1) freehanding on jobs like sanding my porch floor and (2) laid on its right-hand side on a little homemade base with a fence.  With the base, I can do detailed sanding/shaping to lines.  I bought the sander to sand my porch floor, but since then have used it exclusively and extensively for sanding shapes, e.g., Pinewood Derby race cars.  Belt changes are easy, tracking is easy to set and stable, and the dust bag works pretty well too.  This is a solid and well made tool.  Ear protection is a must.
