Neo Geo Pocket Prices

Is there any kind of price guide for the Neo Geo Pocket? Or is there any where else i could try and find the value of Neo Geo Pocket stuff?

check completed items on Ebay for the current market value of whatever you are looking for.

Sorry to say it isn't worth much. I still have mine, even got the Flash Card writer so I can cram 3 or 4 games onto on cartridge. Hate to admit it but when I got it it was so I could play Faselei (couldnt buy the game).
