Personally Ive had better luck with Dynamic than anyone else, as far as building and working like I thought it should. Since Ive moved back to Kentucky though Ive used BTE to do a repair on a starter ring gear of the old Dynamic and they were excellent to deal with, seems a large majority of people in this area think they are by far the best. All I know is lots of people really like them, and that they are very reasonable on pricing.
