I'd suggest going to a big music store if possible and test drive a few. You can get a new made in Mexico for about $400, a Standard American for about $600. The quality of the MiMs are quite good imo, and I bought 2 over the last 2 months from Ebay. I have a vintage American from 1984 that still screams.

There are subtle differences 'tween the American and MiMs, but you'd have to play them to feel/hear the difference. I did a review on a MiM and drew some comparisons 'tween a MiM and an American that might be helpful. But I think the key thing is for you to try one out for yourself.
