I'm considering buying a small belt sander, probably one that uses 1x30" belts. There is a model I'm looking at, made by Grizzly. It's around $60 plus shipping.

Has anyone used one of these table-top belt sanders? I don't really have the room or desire for a stand-alone unit, so it looks like this is a good option for me.

Are there belts available in grits finer than 400? Or do you go to a buffer after the belt sander?

As a side note, it's funny to note the differences between woodworking and finishing metal when it comes to abrasives. In woodworking, 400-grit is "extra fine," but it's hard to find wet-dry sandpaper below that level for metal... The guys at the hardware store looked at me like I was nuts one time when I asked for 1000-grit sandpaper.

Thanks for the advice,
Josh
