my other 2 guitars are an gibson SG Deluxe and a 2004 American Standard Strat and the quality, sound and playability is up there with both. ive actually been doing more playing and recording with the tele lately. DEFINITELY look into one of these. They are awesome especially for the money.
the agiles have a great reputation. I would not buy most of the lower line gibson stuff, except for the faded les paul doubecut w/ p-90's. I think those are a great deal. the cheaper fender stuff isnt bad on the whole (per the mexi-tele suggestion). if you like hollow-body guitars, the ibanez artcores are a very good deal.
I think this is one of those "you got to try some out and see for yourself" type of deals. Or at least give us an idea of what you're looking for, like bridge, neck, pick-ups, and so on.
something like a Les Paul Studio ... even if its beat up it will still eat 95% of the new guitars out ther in this price-range
just make sure its pre 97 ... basically all guitars were driven down in quality around this year (made w/ cheaper parts, huge "pools" for pickups instead of individual cavities etc...).
