I would not pay someone to fix an obsolete pump.
Goulds is a good pump but you will pay more for it. I have no experience with the Water Ace brand; I am more familiar with the Flotec brand at HD. Go on line at www.grainger.com and look at their shallow well jet pumps. It will at least give you prices for comparison shopping.

You will want to check flow (GPM) versus pressure for any pump you consider. You might consider a 3/4 HP pump if you are going to do any outside watering.
