Manual Boost Controller

[rob_drake2]

Alright i'm looking at the boost controllers and I plan on getting the Hallman brand. My questions are what's the difference between the Pro RX (http://www.extremepsi.com/store/product.php?productid=18044&cat=276&page=1)and the Pro (http://www.extremepsi.com/store/product.php?productid=17231&cat=276&page=1) version, if it would be the same as just getting the cheaper ES model (http://www.extremepsi.com/store/product.php?productid=17232&cat=276&page=1) and which one I should go with or which is best?

The pro rx kit has a ceramic ball instead of a stainless steel ball and a lighter spring. It pretty much allows for finer tuning your boost in smaller increments. If it were me I'd go with the pro kit.
