I called and emailed Jim at WH numerous times during the the design process and even sent him a test harness to install. He had a lot of input into the harness. While I can't actually say for anyone to buy from one place over another, Summit is a very good distributor, Jim did take time of of his day on more than one occassion to offer help and/or information. I fell that it shows that he's not only interested in taking your money for a product he sells, he wants the product he sells to be the best it can be. I just thought I'd throw that out there for what it may be worth to some of you.
BI, I'm sure it will be shipped out ASAP.
