Perhaps one that is sold by someone highly addicted to some substance and needs money for his/her next fix? That might mean you are purchasing stolen property though. You can try pawn shops, especially if you live in a major city. I'm not a guitar player though, so I can't tell you what is better a Fender or an Ibanez.
I say the Epiphone ES-339 PRO. It has humbuckers, but with coil-split, so you get humbuckers and single coil tones. It's right there at the $400 price, but maybe you could find a good deal at Musiciansfriend or AMS.
