Ah, shame, thought they'd cost more than new ones with them being so rare nowadays. Seems like you got a good deal though.
O3DS are not rare at all and a 4.x O3DS isn't really something important anymore. Any console between 4.1 and 9.2 can be used and any new O3DS/2DS comes with 9.2 or below. Used ones aren't that hard to find either altho it's always important to ask the seller if he doesn't specify the firmware.
N3DS consoles with exploitable firmware are the rare ones.
