I have a 1080/1400/1900. Last Friday I replaced a small flat bump out roof as a favor for a buddy who is suffering a little in the current economy. The roof was 16'x10'. This was the first time Io use my brand new TS75. Awesome saw. The one issue I had was when laying the first few pieces of plywood and being up on a roof it was a real PITA to connect and reconnect the two rails together for trimming the 4'x8' sheets. They do work perfect attached together however I will be buying a 2700 at some point in the future for those 8' quick cuts.
