If you're not in a hurry then check their site periodically, they frequently have $0 setup specials for their low end servers. (ie $0 setup, $119/mo)
I know you don't need all that transfer, but considering the specs and the size of their network it's a good deal. I got in early about 18 months ago and I pay $79/mo for the same thing.
