Where do you turn in video game systems and games for the highest price

You can trade in your gaming systems in for $100.00"s of dollars but.....I do not recomend trading in the following
. ds, dsi. dsi XL. xbox 360. ps3. or the Nintendo wii. because they are very modern and very exciting.

I do recommend trading in a xbox original gamecube and gameboy you may not get alot maybe $20.00 or something but its better than trading in a modern console.
