my choices- New american standard. Under budget, amazing guitar. But for that price, a used Eric Johnson could be found. A really clean, like new one. Fabulous guitar, whether you like ej or not. Could also get a used srv, or mayer. Both are amazing, and would meet all requirements. Outside of sig. models, I would hit www.davesguitar.com
and check out the current crop of thin skins. Awesome vintage reissues with full nitro thin skin finishes, and the required fret size and radius. A little over budget, but not much, and theres nothing Id rather have for that price.
