I've got a few 504 belt sanders. There's a live auction locally going on this afternoon I was debating about going to that has an A3 belt sander on it.

I've never used one. Do one of you tool junkies have any insights to this particular model? Is it basically just a different case, but same guts as a 504? Is there a weakpoint that makes them not desirable?
