It seems the cheapest option to get rid of the scale is the filter I posted earlier at ~$55.
The second cheapest option I could find was a 35psi, 1gpm pump at ~$50. Unfortunately, it's only 12VDC. The 115VAC version cost ~$100. If you have a spare battery and charger or power brick than it might work out.
Aquatec 2800 (40psi, 1.0gpm, 12VDC) ~$50
Flojet Fl-12V (35psi, 1.1gpm, 12VDC) ~$50
Flojet FL-33 (35psi, 3.3gpm, 115VAC) ~$100

I have an unused "universal" laptop charger that has the 115VAC input and ~15 VDC at about 4 amps. This looks like it might power the DC pumps. These can be bought for about $50. More money if not on-hand. I think assume something like this would work...
