I decided to make a run back to GoodWill and see if I might have missed anything and walked out again with a Sega Genesis 2, Sega CD, Sega Arcade Power Stick, another Master System controller, a Genesis 6-button controller, several Sega power adapters and Hang-On & Astro Warrior CIB.
2014 is has had the best start I could ever have asked for.
