I have had a disk sander and a vertical belt sander combo for several years now. At first, I thought that the vertical sander would handle my stationary belt sander needs. I found out very soon that you do most of your belt sanding with the grain and that means what you really want is an edge sander. It supports the long edge of a board and keeps it flat against the belt.
Well, I found one that is reasonably priced while I was considering the distribution of some woodworking machines (such as the jointer I put on Ebay a couple of weeks ago). I bought one for myself and I have one on Ebay now. It appears to do a wonderful job in tuning up door and drawer edges that I used a plane for. It is aggressive but one of the most controlable power sanders I own. I am betting that there are others that have been interested in these like I have.
Now, I have only had mine up and running in the last day or so, so I am not an expert. I would like to know of those of you out there that have these -- how valuable are they to you?
Here is the one I have on Ebay.
