looking for fan controler

[Corban227]

I need a good fan controller for 6 fans. i'm not exactly sure about what makes a fan controller good or cheap so i could use all the help i can get =D

i have 4 120mm LCD fans and 2 140mm fans

something like this would be cool, but it would be nicer if i had 6 fans controlled by volume knobs

if its possible to get one with a RPM read out that would be nice but not necessary for me

thx
