It's a debug unit. Basically an official PS1 that plays burnt games and runs all regions. It's not really any better than a modded PS1, and they had a likely modded PS1 sitting out on the floor for $15
Last time I looked into buying one of those (because I do want one), they looked like they were worth maybe $150USD (that was a few years ago though). I'd entertain buying one I found in person like this one @ $300, maybe. Value Village is never going to mark it down. And I'll be unsurprised when I walk in a few weeks from now and see its sold. Vancouver has an ample supply of stupid hipsters that have money.
