WTB (or trade): 33 1/3 Series books

An offer for anybody who has a bunch of these, is unlikely to reread them and wants to make a little bit back on their investment: I'd like to buy or trade for these in large lots. Like, 20 books for 75-80 bucks, something along that line. The only ones I don't want are the two I already have (Drew Daniel, 20 Jazz Funk Greats; Geeta Dayal, Another Green World). Sorry in advance if that price is insultingly low.

I'm also willing to trade for these -- as my rolling "for sale" thread starts to get stuff listed, anything you see in there is also available as trade bait for books in this series.

I'd offer to help but I only have 4-5 of these at present (and am in the same position as you—trying to collect more, but not rich enough to shell out $10 per book when I blaze through 'em in one evening apiece).

I have a couple that I will never read again like the Radiohead and U2 ones.
