There's a lot of good choices out there. We're lucky to have a lot of good gunsmiths and custom gun makers pretty much close by to any of us.
If you're on a tight budget your best route may be to scavange up some donor pieces and have your local smith put it together for you. I think it'd be very possible to set up a sweet gun for under $1500.
I'm in the process of doing just that on a 7mm right now.
Pick up a barreled Remington 700 action, have it tefloned, get a good stock like an HS, work over or replace the trigger with something like a riflebasix, have your smith true it all up, and odds are you'll have a sweet shooter for around a grand. If your still not satisfied with how she shoots take the $500 you have left and go for a custom barrel.
I hear a little good and bad about every custom gun out there, but it's a lot like listening to guys argue about truck brands.
