Reply to Sliders for pitch control using UMC32

Hi Guys,
Im new to this community . Im currently looking into building a midi controller for traktor using a UMC32 (or even two of em!)

What i cant seem to find is some high quality, stiff 100mm sliders I could use for pitch sliders. has anyone found any nice ones on their travels? something with the feel of a technics one but maybe longer would be nice.

Anyone else used the UMC? im a complete beginner so any examples of other peoples setups would be nice

Cheers
Neil
