Get real. This dude sells new home systems for $1,000+
The fact is they will be $400 at the very least, and they will sell out faster than you can say "I wish I got a boxed system while he had them". These are new CD systems, which means it hasn't been running for years like all the second hand systems people own. People pay out the nose for new releases when it comes to games, consider if he sold them at $400, these will fly off the shelf.
Hell, I've always wanted a CD system but never wanted to buy one because I was afraid the unit would shit itself. Even the $400 price point would make me want to buy one, and I'm sure there are many others like me that would just jump all over this.
