I have a Team 1, 35 amper as well, great unit. Only gripe it is kinda awkwardly built.
I just got one of the ones like Burbs mentioned above from ramboy.com
13 amp unit with voltage adjustable from 10.8-13.2 for $26.50 shipped you can't beat it. Plus it is nice and small and lightwieght, perfect for taking it to the track.
Only complaint is that the unit does not come with a cord, so you have to find a cord (I used an old lamp cord, 2 prong) and hooked it up and she fired right up.
Great buy if you don't need a lot of amps!!
