This is how I think about MODs ---
1) Hori pad sucks - (analog stick wise) The MOD features are good but the controller is very hard to get used to for me. The analog sticks are very small and not as smooth. (Ive used reg. controller since PS3 came out)
2) CustomPS3Controllers.com - A good site for PS3 Mod controllers. Expensive - about $110 or $55 to send in your controller and wait.
---- Also I think - 2) They have Mods for COD5 W@W . I think. Someone check it out?
