Motor help

Completely forgot I had a atomik fireball 21t that a buddy sent with brand new brushes a while back. Slapped it in and dropped from 20t to a 18t pinion and am very very happy. But I still want to go with a stronger better motor soon. Anyone have any brands worth it? I absolutely love both of my torquemaster pros in my two crawlers and am tempted to see what Holmes hobbies could do for a drifter but that's a few more dollars than I have to play with this month anyways. If I saved a little here and there over the next few weeks I could grab a 80$ motor. But really want to stay brushed for the smooth start up.
