Need to replace PB4, is there a better booster pump?

[aerangis]

After 6 years of use my PB-4 booster pump motor has failed. I can get a replacement at a local Leslie's for $299 but after researching boster pumps online I noticed there's a new model pump that was released in 2011, the PB-60. Can I easily swap my failed PB-4 with a PB-60, are the voltages compatible, and are there any issues that would preclude using the PB-60 instead of a PB-4?

If I have to replace the booster pump I want to get the best pump possible.

I think there may be some confusion there. Polaris makes two pumps the PB4-60 & PB4-60Q.

They did change the design of the PB4-60 housing to look a bit more modern a few seasons back. The "Q" version has a housing that makes the pump quieter.
