Good word on the Trimetric Klenger. It just so happens that the guy lives just a few miles down the road from me and appears to work out of his house. The Link 10/20 seems to be much more common, but the Trimetric has some nice features. The one concern that I had was that it utilizes LED displays which would consume a bit more power than LCD's would. I suppose they can be turned off, but constant display might be nice.
As far as the Progressive Dynamics IntelliPower 9100's, I went with the PD9160V (60-amp) with the charge wizard mainly because it would fit nicely into my older Magnetek Breakout box (fuse panel). Also, having only a slide-in camper, my electrical requirement are not that demanding.
