I do really believe with any professional (farrier/vet/barefoot practitioner of any kind) you should go by word of mouth and recommendation. Go and see their work if you possibly can. My partner was recommended to me as the best horse vet in the area (and he is!!) and now he's a fantastic EP too!! Lucky me!!!
As to being cheaper, I wouldn't actually say that because Alun attends so much CPD all over the place. I think the farrier was way cheaper (even with shoes) and was so much easier because we knew very little and left it up to him (more or less). But once you start on the road to finding out more, it's compulsive! Our ex-farrier is a great guy and is still a friend (and neighbour), he's even been on a few days of the courses (we used to run most of the KC La Pierre courses here in Wales) and really enjoyed them, particularly the dissection. He even brought a couple of friends along and they are very complementary about what we do!
