Best Automatic Pool Cover?

I have a Save-T Cover II motor and a Pool Cover(? I'm told they are out of business) Tube and rod that the Save-T Cover Motor turns. The tube broke. Once Company said they can repair the tube and side brackets by finding old parts for $1388 or a new Cover Pool Save-T 3 (new motor, tube, and everything except the fabric cover --mine is still good) for $4705.

I've got similar quotes to install new systems minus the fabric. I've been quoted several brands by contractors and am trying to figure out what is the best. Automatic pool cover, Cover pools second approximately $450.00 and Cover star. As between these and the Save-T Cover, any view as to which one is best?
