Yeah, that's a fair price, if some of them are in good order. No one is necessarily to go gaga over them, but Kirons are good, and some of them I bet you could sell off here to get close to cover the outlay.
Basically, you could probably have some fun with those and not end up tragically in the hole or anything, if your time isn't worth too much to go get them.
Some of those Albinars are pretty good, actually, and make an interesting 200ish 2.8 lens on crop. Something I plan to try myself in one form or another. Where you gonna get that.
(Also, on the Promaster, ...So happens I've found that on Ebay it's pretty much impossible to get even the cheesiest no-name wider-than-28 even in canon FD mount for anywhere near what an obsoleted-toy should cost: and even the best FD lenses suck out loud on the best adapter you could get. Something that'd ctually work on digital, well, that'd probably cover you. It's silly, but it'd sell. )
