The 1100 is a decent little phone, basic, simple/easy to use, no frills. Also fits in a shirt pocket.
Their GSM coverage is excellent, it roamed in places where I did not expect it to.
Affiliated commented about the per-minute rates. In my opinion, I think it's worth the extra cost, just to have the excellent coverage area with TracFone.
The other TracFone GSM Nokia model is the 2600 which has a color screen, and I've seen it available at Target in my area. I don't know much about the TracFone Motorola models. With the exception of my first mobile phone (then GE-Ericcson, 1995) and an LG I had on Cingular (2003), all of my mobile phones have been Nokia.
