Reasonable Price for TC-20 and elmo st800?

[retrogrouch]

Hi all,
I am going to sell my Goko TC-20 and an Elmo st800 on my local craigs list, to help pay for some new (to me) 16mm film gear. I had a look at e-bay, and the prices were all over the place. ( the tc-20 from $400-1000, and the elmo for $100-350) I got great deals on the stuff, but had to do a lot of leg work to find it. I don't want to sell this stuff through the mail, and would just like find out was is a reasonable price for this stuff.

Thanks for your time ( and patience with this somewhat obnoxious question)
