I've recently gone down this road, and I decided to go with Indy Fab only because I don't see that many. But, I ruled out all the frame makers that didn't have a dealer near me. I wanted the piece of mind just in case anything went wrong I could take it to the LBS and get it taken care of. It's a tough choice. For me I had the option of Serrotta, Waterford, IF and Seven. They're all really good. I got the full measurement, fit bike and for the IF. I would highly recommend getting a full fitting if your dealer doesn't offer it I'd pay the $$.
By the way, if you like lugs, Waterford is a great choice. They also use silver for welding (brazing) which takes less heat to work, which means less frame distortion during manufacturing.
