Should i get the psp go?

So a few days ago I was out lookin for a ds in the local old electronics market ,I was sure i wouldn't find a ds , but i stumbled a upon a psp go which is something I was never expecting to find where I'm from , so the psp go still has the box but it's kinda worn out and it has everything inside the box the manual charger a block thing everything, and the back has lil bit of scratches and it cost like 78$ should i cop it or nah?
