I'm running out of time to debate, thats why I needed to make a decision now, the weather is going to chage in days/weeks, and really need to finish up the HT project, as I will be stuck in the back yard on a few big projects, and still have about 500 square feet of mable to install and grout, can't spend weeks more on the HT system. lol

The 2900 was an expensive way out for a year or two.
