Next step up from a Feigao?

Hi all,

Have some money to put into a truck and you guys have helped me make a lot of the decision - now it comes to the heart and soul of the truck - the motor and controller...

I'd like to go one step up from the Feigao/9920 setup and was considering a Lehner. Do I have to go with a 1930/40/50 or will something like a Lehner Basic XL2800 be a good step up? I don't really wanna spend 250-300 on a motor to start but I certainly wouldn't have a problem spending double what a Feigao runs for (~150-175ish)

If anyone can offer any insight as well as tell me how much of an advantage there is moving away from a feigao i'd appreciate it.
