Out of these, I have a GBA, a GameGear, and waiting on the SwanCrystals. Also planning on getting a neo geo pocket color and maybe a game.com soon. Use to have a nomad but sold it on ebay many years ago.

I'm not really a handheld collector, mainly just consoles, but I have the Game Gear, Nomad, Tiger and a GBA.

GBA SP is it for me. Tons of playable greats, new and old.

Not much right now... and yes, abbreviations are my friend (it's late/early, otherwise I'd type the whole names out).

I'm seriously considering buying a Wonderswan Color (a Crystal if I can find one) from JapanGameStock.com, but I'm still confused by their check-out system. I want to do it, and I think - I THINK - I can do it through PayPal, but I'm not sure, so I'm holding off on it.

I own:
