Solid logic. Dude, re-read the responses and understand that people aren't giving you advice pulled out of their asses, they're trying to help you understand why what you are asking for is very difficult to find. I've been around the custom shop block a few times and I'll tell you straight up in your price range, if you're not going Carvin chances are you're going to get a guitar of so-so quality if you're shopping for a small luthier build "on a budget". If you want something high quality in a lefty, you can either spend $1300 for a Carvin or pony up and get something in the $3K range to get quality with higher levels of customization. Guitars in the low range with a small builder just won't have the quality you're demanding.
THANK YOU. You're the first person to give me a straight answer. Not to say I didn't appreciate everyone's responses, (especially those that gave concrete recommendations), but it seems as though everyone is quick to judge my decisions before they're willing to help me out. I wanted to know if Carvin was the only poor man's godsend in the realm of customized guitars.
