my vote is with the stinger. From my memory, the AE unit doesn't allow you to open the motor up and skim the comm with a standard lathe so changing the brushes is useless.
The stinger does work well for quite some time and puts out good power. Heck, you could almost do a stinger spec class LOL.
I would say a good replacement motor would be any of the 19T ones currently out. The Team orion element both standard and V2 style are good, with the standard having alot more torque.
I also like the Reedy Quad Mag but you have to service this one more. Great motor too.
