I think the going rate is more like $10 each if in good condition, with maybe a deal on larger lot sales. You can unload them on largeformatphotography.info/forum (in the buy & sell area) or here in the classifieds. They sell at good prices on ebay too. Just list them in relatively small lots (say lots of 5). Stagger the listings too - don't just list them all at once. If you list a big lot you'll get much less for them, and if you don't stagger your lots by a day or so you'll also lose bidders. If you just want to get rid of them on the other hand, ebay is a sure fire way... as is here. Hell I'd buy a couple.
