These are the places I have had experience with or have had friends with extensive experience with:

But rather than list them all, what I want to do is to create a list of shops, and who got motors from them and then their rating on the customer service.
0 - Never got my motor1 - Got my motor, and it was horrible2 - Got my motor, and it had a few issues3 - Got my motor, and it was decent4 - Got my motor, and it was very clean5 - Got my motor, and it was very clean, and the customer service was top notch!
Use your best judgement and please be honest.
Ex.
I got my motor from X and I was very happy with their service, and my motor was very clean and ran great!
I'd give X a 5
Ex. 2
I got my motor from Y and I was very happy with their service, but my motor was very dirty, and had a cut wiring harness, but it runs great!
I'd give Y a 3 since it was missing parts, but the motor still ran good.
The reasoning behind this is everyone has their favorites, but this gives a look further into it.
