I am not sure I follow. A bearing and seal costs about $17. That with an hour labor and you are rolling. Why do you need to spend $450 plus on a new pump? You have to watch some pool places (Like Leslies) because they like to gouge you on the little stuff.
A quick 5 second google search found this:

I found that with my pump they didn't show the motor bearing either. There will be 2, one on each end of the motor. Take it apart, pull the bearings off and take it to a bearing supply house. Mine were $6 each so I replaced both while I had the motor apart. If you don't have the right skill get the seal from your local pool place and hunt down a local electrical motor repair shop. They can easily change the two bearings for you. My point being they make these pumps with common parts. It's not likely your pool pump is going to have some one off NASA built bearing in it.
My motto is that it is already buggered up so you have nothing to lose by trying to fix it yourself. The worst that will happen is you have to buy a new one anyways..
