Just remember you get what you pay for. Cheapest isn't always going to be the best or safest. Not going to knock a particular supplier but there's one who advertises in one of the rodding magazines at prices far below anyone else, however judging by complaints at the BBB and on many boards, what you get is not what you are made to believe you are getting. If someone is selling something for several $100 less than every other supplier there's usually a good reason.
