Try looking at the axis line of pedals as an alternative to the 9000. I play a brand new 5000 on my practice kit and have had an axis on my studio kit for years...I'm not a big fan of the 5000 personally.
i have the 5000 and its plenty good my friend. its as quiet as you can ask for and it responds nicely to any adjusments you might make. i replaced the beater with a round felt ball danmar beater but its all good...just a preference thing. i got mine off of ebay in great condition for 120. saved a few bucks and got what i wanted.
