"Dr. Servo" Tester
Neat $36 "Dr.Servo" uses a gyro sensor to monitor servo rotation during diagnostic testing. Don't need, but LIKE.

Hobby King's version is $32.95 and is a better color IMHO!

Now $7.11 my friend. They must watch for ya to get people interested and then bump up the price. Getting some kickbacks here erco??? ;-)

$7.11 PLUS 77 cents shipping. Highway robbery!
@erco - Got them my two today - Nine days from order to my mail box - perfect condition! Just $2.90 and free shipping - China to Louisiana - HOW IS THIS POSSIBLE?
It also has neutral/centering mode and oscillating mode, just like the $1.50 testers.
I use testers like this a lot in mechanical development for checking range of motion. Particularly handy for developing one-servo bots which locomote from servo oscillation.
Best price still ~$7 shipped.
Here's a $5 unit with an LED display. I haven't tried it. http://www.ebay.com/itm/G-T-Power-Digital-LED-Servo-Tester-for-RC-Car-Trucks-Planes-Helicopters-F05767-/252433717190
