I definately sympathize with the OP feeling uncomfortable with sending the motor back to someone who displayed shoddy workmanship and created the problem in the first place. It's always much more respectable to do the right thing the first time, until having to when peer pressure forces your hand. Kinda like having a dentist appointment to get a tooth pulled that is bad and they pull the wrong one, novocaine wears off at home and you notice you still have the toothache...... You probably go to another dentist next time.
I agree plus your not talking about a couple bucks here. That is a lot of money in my book for it not to be done correctly the first time. Trust is a major issue here from what I see.
