I am looking for a source of hobby servos of the sort that one
installs in radio controlled model aircraft etc.  I would like
to construct an insectoid robot like MIT's Ghengis, and the best
servos seem to be the hobby type, which is what they used.

Can anyone suggest a source of these for less than $11 a piece?
My local hobby shop carries the Hobbico standard size for $10.99
a piece and I'd like to pull the cost down from this since a 
6 legged insectoid will take 12 motors (one alpha, one beta)
and I'd prefer not to drop $130.  Plus the guy at the hobby
shop thinks I'm a goof.  =-)

In addition, can anyone recommend circuits (there was one in an
electronics magazine a few years back) for driving these servos
using TTL?

Thanks for the info in advance...
