Good evening from Maine. I just retired this year and thought I would get back into my old hobby. I dug out my old whites coinmaster 1 put in a new battery and it still works. I also ran across a tesoro compadre at a flee market for $20 and it seems to work fine also. Not sure if the whites is any good or if technoligy has outdated it so im also looking for another machine. I haven't read much about the tesoro silver umax. would it be a step up from the compadre. Is it worth the extra money over it's little brother? Anyway looking forward to better weather up here. Ernie
