My $.02.
A friend of mine bought his printer as a kit. The extruder gear was a printed ABS part and his motor was, IMO, undersized, I don't recal the exact rating. It would get so hot after about 20 minutes of printing that the gear would melt and start to slip on the shaft. I don't recall if he figured it out or if he just put a fan and heat sink on it.
I use oversized 2.5A steppers but I have the problem of keeping my electronics cool so my drivers don't shutdown or lose steps. I think a good compromise would be something in the 1.4 - 1.8A range, won't get hot under constant use and won't tax your drivers as much.
