At this point the only pump I would recommend is the Aquatec 8800 or maybe the equivalent Shurflo RO pump. There are a lot of imports and clones out there but most are not the same quality and do not last long term. I have been using an 8800 set at 95-100 psi for the last 7 years with zero issues and would not hesitate to buy another if the need arose.
The aquatech 8800 seems to be the standard when it comes to booster pumps. Just make sure when ordering to get a pressure switch along with the pump to automatically shut it off when the float valve closes.
