What is Mach 460 worth?

[94GTLaserRC]

Someone was interested in buying my Mach 460 (head unit with cassette player only)

What would you think I should ask for it, and then "settle" for it, given that it's just kinda sitting around?

Thanks

I dont know man but I know i had put one a friend gave to me (both the upper cassette am/fm reciever and lower cd player) on ebay at 10 and bidding went all the way to 90 something. I guess it depends on how much you like the guy, lol
