Lowest selling system you own/owned

[Burning Typhoon]

Out of the 14 consoles I own, the PSTV/Sega Dreamcast are the lowest sellers. Depending on if the PSTV counts as it own console, and not a Vita. I couldn't pass it up for 20 dollars, though, wtf. Sony was doing a flash sale on that thing on their website to get rid of them, lol.
