I went the expensive way so as to have original 7' lengths (custom cuts), and it only cost me $360US then. If I had gone with 6' lengths (normal sheet lengths), it would've only cost just over $200, but I wasn't sure it could work. Now after doing the job, I think it could have. Also, I went with 1 7/8" vs their 2", but that WAS a mistake. Get the 2". I had them hollow out the bottom to allow room for the bolt heads, but the 1 7/8" width did not allow enough room for the bolt heads and I had to countersink each spot separately. I believe the 2" would fit better.
