Dome Hinge Servos
using the standard size servo from tower hobbies. 
using the Pololu servo controller there is 0% servo jitter with mine. No whine, no nothing.
The servo brackets are home grown. They are made from some 1/16" aluminum flat stock.
The linkage is the Dubro heavy duty set. JAG was nice enough to lay out all the parts needed in his PDF he sent out yesterday, or was it the day before... anyway... I didn't actually buy the parts he laid out, I bought some aluminum tubing and 4-40 and cut my own.
Here is the link to the Dubro set.

The Hitec HS-425BB is a standard size servo but features dual ball
bearings on the output shaft. Most servos like this have plastic
bushings which over time get sloppy while dual dual ball bearing servo
will remain very precise.
for a little more money is the HS-125MG. It has
dual ball bearings, metal gears, more power and is super thin. It is
also designed to mount flat so with the smaller size will fit great in
some tight spots. I really like this servo a lot.
You can get a Hitec servo chart here:
