Slowly working on a Gamecube collection; I have the 3 DOL-001 colors released in the US, (indigo, black and platinum, and 001 is the original version with the digital output on the back) the Japan only component cable, a NiB white Japan only controller with the longass cable, the GBA link cable, and an original Wavebird. I've probably forgotten some things...
Have a handful of games, but those are really for me to play, not for display, and I only have the case for a few. I mainly want the rare hardware anyway. I want a Gameboy Player, but I'm not willing to pay the absurd prices for one with the disc. I want the LAN adapter, mainly so I can write/host a server for Kirby Air Ride on my computer and play with friends over the internet. And I definitely want to pick up a Panasonic Q at some point. I don't see any practical point in getting the ASCII controller, but if I find one for really cheap, I'll pick that up too.
The Gundam Char's set...idk, they seem to have come down in price...a lot. Still more expensive than I'd be willing to spend, they're not items I actually want, they're just recolored (ugly salmon pink-orange) with a logo slapped on, they're boring, they do nothing interesting, or different.
My collecting is mostly practical, I use almost everything I own. :P
