I did a search with the part number and decided to give your company a try.

Found exactly what I was looking for and for a good price. The checkout is nice and simple and easy to use. However, when I sent them an email before my order shipped saying that I need to have one item removed from the order, I never got an answer and my

great shopping experience but from my online buying experience is that if you place an order of 200 or more shipping should be free but that's just my opinion

Very good price, fast shipping, A+
