is the proform brand pump any good? its about 50 cheaper then the CSI and comes on a housing. anyone had any experience with them?

if you go cheap, you will regret it. i recomend the mezeire. it is the most expensive of the 3, but it has the best record from what i've seen. i personally know of 3 people who have mezeire's and have been using them 4-7 years problem free. on the other hand, i know 2 guys who have CSI (now CSR)....they are both on their second. one lost his first year, and the other lasted 3 years (probably 15-20k miles) and took a poop. people will give different opinions, but the mezeire hardly ever gets a bad remark.

I had the CSI (now CSR) pump on my z up until i sold it (about 2 years) with no problems. Once my wp goes out on here, I'll probably opt for a mezeire though. You get what you paid for.
