The only regret is that I didn't have it years ago. Bryan Patton Bryan Patton Contracting Mt. Auburn, IL This calculator has saved me countless hours and money...I just wish I could find more ways to save as much...One of the most valuable tools I own. Douglas M. Buesking Booker Associates Belleville, IL Was doing a house and the roof span was more than what the blue book had available. Went out and bought "The Ultimate Calculator" and have not used the blue book since. The instruction book is very user friendly. I use the calculator every chance I get which sometimes is not enough. I am even thinking about getting a second one for my lead carpenter. In my opinion, even at twice the price, it is still very much worth the money. Michael C.
