If you are spending serious $$$, you may want to look at
commercial actuator suppliers like below. Some have feedback pots
for position indication. If you want to go really cheap and DIY,
you probably can hack a standard servo to do most of what you
need using the threaded rod. I'm currently looking at a similar
simple DIY setup, but I need a roller skate wheel bearing to use
as a cheap thrust bearing for the threaded rod. WalMart no longer
carries replacement skate wheels, so I'll have to expand my range
of parts suppliers. ;)
