I've got an '05 Custom. It's an MIK, not MIJ. Odd.
The '05 is still all stock except for a toggle switch and saddle. My '08 Honeyburst has new toggle and aftermarket pickups. SD Duncan-Distortion and '59 in the bridge and neck.
Used standards around here get listed for $275-$300 with or without a case. Pawnshops are higher here than private sale, so I imagine it's in line with them down here. I think the pawn shops try to sell for max eBay price around here. The Ebony Standards go for $429 new, IIRC, so if you got one with a case and was already set up to play nicely, you didn't do too badly.
Enjoy your new guitar!
