Yes I did. Price for either company size that I purchased was about the same. I went with US Steel because the salesman was a lot more professional and very knowledgeable about the product. The salesman for Carolina couldn't answer all of my questions without having to call the main office. And US Steel had a definite date for install whereas Carolina couldn't guarantee the date.
Googled US Steel and didn't come up with anything specifically that. Do you have a link for where you got yours?
