My 2cents,
I'm really partial to the JR 9000T & the DS8711, I also have a few Hitek Robot servo's that have served very well as with the 7955's. They are all great servos.
Do yourself the favor and spend at least 100.00 or so and get the highest qaulity strongest servo you can for your money. It is a serious investment yes but a wise investment. You cannot substitute and so-so servo over a qaulity servo in a demanding application. With the extra money spent you'll also be getting a company that will stand behind their product and usaully warentee with no questions asked for up to 3yrs !
You'll also thank yourself for getting a badassed servo w/300+oz of torque after you wheel it around a few minutes. You will be saying to yourself, "my god this servo is awesome".
