if you have the 645 id get the 625 for throttle. i hate plastic gears ! if you plan on using good brakes then get the 625 it will be good.

I use a JR 590m. It has more than enough torque for wheel locking brakes and is fairly quick. It's a good deal for $40 and will also make a decent backup steering servo. I have had bad experiences with Hitec servos so I personally don't buy them anymore. I had a 605 fail after just a gallon of fuel, and I went through three 525's on throttle that all started glitching after about 15 minutes of use. Between planes and cars I have owned about 20 JR servos and they have all been great.
