I have had the SMC kit for about two years, just recently the controller started acting bad, sent the kit back to SMC and recieved prompt and curtious service from Steve. Though many might be able to replicate a kit cheaper, IMO you can't put a price on a top quality product and exellent customer service. I would recommend this kit to anyone who is looking into buying an alky kit Thanks again Steve for your dedication to having a great business.
