i can give a thumbs up for Oil City Pickups, i have a humbucker from them fitted to one of my guitars. The reason you may have never heard of them before is because they only sell direct from their website and each pickup is hand made in the uk. They come with a lifetime guarantee which is nice to have and there is a contact number on the website if you want to phone them. I did and i spoke to a guy called Ash who was really helpfull and actually made my pickup too.
I recommend you at least give them a call and have a chat about their pickups before deciding what you buy, it's not often you get to talk to the person who is going to make the pickup for you before you buy it.
