Servo Strength

Alright, so i've been out of the game for a while and most of my parts are being used. I now need to order several servos (12 in total) for a hexapod build I am planning. Each leg will have 2 DOF, with one standard servo (i'll come back to this) connected to turn the leg right and left, and a more powerful servo (coming back to this again) to move the leg up and down. I'm not exactly short on cash right now, but I really want this to be a relatively cheap build. I only have one standard servo on me right now (a gws s03n STD) however i've been looking at the hitec servos offered by trossen, especially this one: http://www.trossenrobotics.com/store/p/3289-Hitec-HS-322HD-standard-hobby-servo.aspx

the only difference I can see is that the hitec servo is 5oz weaker at 6v (.3 pounds or something). I don't see this as being a major problem, however i wanted to get some second opinions. 

The second servo i was going to use is the more powerful hitech HS645mg found here: http://www.rcsuperstore.com/ProductDetails.asp?ProductCode=HRC32645S&click=2

i'm assuming that is a legit site although i have never used it before. Would anyone have a cheaper recommendation that I could buy without sacrificing power?

cheers for the advice
