I have a Rampmaster II. When I purchased my furnace and spoke with Tim Z., I was not convinced that the Setpro had the program segmentation or flexibility that I sought. Evenheat's site was atrocious, lacking detailed information on either the Rampmaster or Setpro. Fortunately, RLinger was willing to share his experiences about the Rampmaster and I was convinced that was the route to go and still am.
I just took a tour of their site and see that things have changed and that there are now detailed manuals for both the Setpro and the Rampmaster. I suspect that Evenheat did not like the fact that a lot of people overlooked the Setpro and chose to upgrade to the Rampmaster. The very fact that they offer their knife making furnaces with the Setpro ensures that it is a more profitable controller for them. They only charged me $100 extra for the Rampmaster, but rumor has it that they do not like doing the upgrade and may not allow it in the future.
A quick comparison of the manuals shows me that the Rampmaster, IMHO, is still a lot more versatile. It can store 6 programs rather than 4 for the Setpro. That alone is probably worth the money to me. Other items that the Rampmaster has are delays and alarms. While the Setpro may have them, they were not obvious in my quick perusal of their documentation.
Bottom line: if I was buying an Evenheat today I would still go with the Rampmaster.
