There are quite a few good doctors that aren't recommended on this site tbh. There also are a few that are recommended on this site that are a average at best.
Just search for the thread where everyone names their top doctors and choose from there. I certainly wouldn't get a transplant in the UK though. Your budget may be a problem though as i think you'll need more than 1,500 grafts and going to a cheap doctor is a bit of a gamble.
