I'll take $165 or obo for the 250 GB Hard drive and the HD Advance 2.0. Here's a link if you are not familiar with HD Advance. http://www.hdadvance.com/hd_advance_whatis.htm
I'm not sure what the Gamecube Broadband adaptor is worth. I picked this up when they were hard to get and I never opened it because I don't have a game cube. Make me an offer.
