Then you are much more limited. I just scoured the sources for the same thing and found only the 3 listed above and another, A3 I think. They are all within $10-20 of each other. The Thompson is shiny black and rather bulbous, The Bontrager would be my next choice, but the Ritchey WCS 4 Axis seems to have the best reputation and mine feels great. They generally sell around $80 with a list of $99.
These guys have a very wide selection and a few I didn't find before, including a 10 degree, a 23 degree and a 30 degree.
