FYI- The Squier mini is OK in quality. If you want really decent, look at the Ibanez Micros. They look just like a mini RG, and now the current version even has a neck pickup that is actually not a pickup but a very small built in amp. It's a trip.
If you want even BETTER quality, most people agree the ESP mini Kirk Hammett signature guitar is where it's at. You don't see them very often, but Musicians Friend has them.
Personally, I am building my own design, in mini form at 19.5" scale for my son and it is nearing completion. I'll put up a build thread on it soon. It looks like a blend of an LP, a strat and a tele, and is built to full high end guitar specs (solid one piece white limba guitar and neck, ebony FB, 24 frets, one EMG passive).
