I'm not sure how much he fetches built normally, but I consider $20 for a RS quite cheap to me, especially considering a MIB version apparently sold for $200. Mine may be built, but he's in great condition and everything's there. Okay, so his motor did explode when I took him apart to clean him up, but if you cast your mind back a few posts you'll remember I got a second OER Spineback in my last lot. Motor problem sorted.
For the record, here he is with this box he was shipped in. Just him, a little bubble wrap and a ton of polystyrene pellets. No joke.
