China made torque motors, which ones are good?

[DanHS]

I'm upgrading my old UTG MP5 with some China made aftermarket parts (except for the hopup and barrel), I'm looking for a decent torque motor, I'm trying to keep the costs as low as possible since it's only a clone gun that won't be used all that much, so I'm not spending over $30 on a motor. My choices for a China made torque motor seem to be JG high torque motor, Element Ultra Torque motor, or maybe this 5KU Ultra Speed Custom motor. Anybody have any experiences with these motors? There's no point in spending the money on a nicer motor if a cheaper China made one will do the job well enough, this is supposed to be a cheap gun.

I like the JG one, That red bell one isn't high torque but more of a balance from my findings, get the blue belled one, it has more torque. I heard good thing about 5KU(matrix?) but QC sucks from what I heard :|

I dunno how you'd get your hands on one, maybe if someone breaks a gun, but the stock A&K motors are high torque and really decent.
