Sandy ... that ULF-28 looks great! I was trying to put together a vacuum frame set-up using a second-hand NuArc device and trying to hook up a vacuum pump, etc. Looks like a hassle, especially since the rubber mat is cracked (another post on APUG about that) and I am not an electrician nor a specialist in getting this stuff going. I just want something that works and is efficient. Better yet, Amergraph even has a discounted rate for members of APUG!

I did notice the conversion option for using low-power tungsten. Is the light diffused in some way to avoid hot-spots? I plan to use this for 7 x 17. *** Just read the article on Unblinking Eye. I think I'm sold!! ***

Thanks again!
