Yeah, what Jason said.
That Hayward SuperPump looks pretty good. It's easy to work on and parts are readily available.
Run the pump motor 'til it fails, if you can tolerate the noise. Then you can unbolt it from the pump, take it to a local pump/electric motor place, and get the motor replaced for around $200. I had to get mine replaced in May - in by 9 out by 4. Easy peasy!
What's wrong with your filter? It, too, doesn't look very old.
Please disregard my comments if you've got money burning a hole in your pocket and really want to spend on your pool!
Cheers!
