I have a opportunity to purchase a MC2120 in pretty good shape from a local collector and was wondering what it was worth. It has no case, no manuals and no box. I was obviously looking for a 2105, 2125 or 2205 because of the meters and overall styling, but because the fellow wants $400 I figured I could do without if that is a fair price. Also, since its pretty much a 2125 without the glass, how much do those go for? and is it worth the extra money? Another question is what is the desire for this particular model if I were to find one with the meters? Could I get my $400 back?
