What would a complete (CIB) Atari 7800 collection be worth? I'm only missing the box and manual for Titlematch Pro Wrestling and the three HES releases. Also, my Tank Command box has some water staining in the corner which may cut down on its value a bit.

I have a few homebrews as well like Klax, Missing in Action, Beef Drop, Programming Cartridge, High Score cart, and an NTSC Sentinel (made from a PAL version). I also have a few other misc. carts like the '7800' 32 in 1, the signal tracing cartridge, etc.
