I like the D5 Vario or the MCP655
Stay away from the Micro Res they have a cracking issue. Also wait for the right pump like Verran said or go with the MCP355 which is a pretty decent pump as well.
Possibly but I would never want to take that gamble. BTW the cracks happened at the same place with all of the people that I have hear from. "Everyone over tightening the same screw???? Hmmmmm
If you overtighten the mounting screws and or put the correct amount of washers in place on the screw I can see it cracking. Mine are tightened hand tight and I have no problem with the one in the wife's rig. A little care goes a long way
