Can you help me price my consoles/games?

[awake]

I have some retro consoles/games that I'm trying to sell to local retro gaming stores (Toronto), and almost every one of them I've gone to has said "tell me your price" which usually means "I want to try and rip you off".

I'd like to know how much what I have is worth, so I don't get ripped off by these guys. If anybody could tell me their approximate value when being sold to a store (per group of items ie. all Sega Saturn stuff, for everything together, or however you'd like), I'd really appreciate it.

Here is a link to the pictures of the consoles/games I have: Pictures by awaketoit - Photobucket

Here are some notes that I hope will help:

PS2 comes with net adapter, remote & its receiver, is mod chipped, no original manuals, but has box
Sega Genesis no box/manuals
Sega Saturn no box but has operating manual and stickers
Nintendos have no box/manuals, a/c adapter for 1, a/v cables for 2.
Couldn't find Gameboy original power adapter, no manuals or box
Everything else (games/systems) has all original documents and boxes, but I only took pics of the N64/Sega ones
N64 comes with expansion pack (still has regular system memory as pictured), memory card for controller also.

Thank you for your time.
