For a rack closer, or governor "nudger" or flat out electronic governor, this servo looks like a great deal. It's metal gear, coreless motor, high torque and speed. $34 incl. shiipping! Note the satisfaction guaranty, including return shipping. Impressive.

Looks to be similar to this one, available in the UK: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220543651600
I'm assuming that "15 KG STALL TORQUE" is roughly the same as the 208 oz/in quoted in your link...
EDIT: It is the same, 15kg/cm is quoted in both listings :)
Also worth looking around on eBay for a better deal; e.g. here's a 4-pack of the same for less than 40 quid delivered (within the UK): http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=370213902366
Also available from Hong Kong (£27.50 delivered to the UK..... if you want to take the risk)
I'm not sure if the aftersales is as good as the one you linked to though, Bruce...
The JR servo is also much slower- 0.2 sec for 60 degree transit. But that's a good deal on that servo.
