The meter SteveV has referenced looks like a pretty good buy -- lots of functions and a data hold function. You would have to capture the amperage during the servo transit, but unless the meter takes time to stabilize, it might work sufficiently well for your needs. As noted, it also has a 20 amp max load -- most less expensive meters will manage only 10.

Circuit Specialists (aka: web-tronics) has a wide range of items -- some priced a little higher and some priced a little lower than other E-retailers -- but generally they have a good selection and are competitive.
