Mercury drugstore tube tester

[radiotvnut]

There's a Mercury drugstore tube tester, that looks to be from the '60's, at the flea market. It has a bunch of tubes with it; but, most of what I saw looked like off brand tubes. The tube tester is turquoise in color; but, it looks like someone cleaned their paint brush on the door over the tube storage compartment.

I wouldn't mind having one of these; but, he wants $175 for this one. Actually, he wantend $250; but, said he'd let me have it for $175. I may be wrong; but, $175 still seems on the high side. What do you think?
