Considering selling some equipment

I'm curious if anyone thinks this is worth the effort, I've got some used and older equipment that I'd like to get rid of in exchange for a new (or gently used) Canon XSi, T1 or T2 frame. I don't need any lenses.

Here's what I've got:

EF zoom 75-300 1:4-5.6 III 58mm
EF zoom 80-200 1:4.5-5.6 II 52mm
EF zoom 35-80 1:4-5.6 III 52mm

EOS Rebel G 35mm frame, barely used at all - maybe 200 shots.
EOS Rebel XT DSLR 8.5MP, used, 4400 pics taken. Great condition, though.

Anybody have any idea what these are worth today?

I always check eBay to see what equipment is selling for. If you do sell it, please list it on the PhotographyREVIEW.com camera classifieds. A basic ad is free and members who use the classifieds say they work well.

OK, looking at ebay prices the parts I have listed only run up to about $550-650 on a good day. Heck, the 35mm Rebel G only sells for $25 or so. Wow. Was quite a decent frame in its day. Bummer, was hoping I could reach a t2 price range, just don't have the extra cash to make up the diff.
