Looking for high quality, large faders

I'm looking at some options for building a MIDI controller using a Brain/Brain Jr. The goal is to build something that is as generic and adaptable as the Alias 8, but with bigger faders. I'd like to get some well-made, high quality parts that also have a good size: 60mm or up (preferably more like 80mm).

Does anyone here know where I could get faders/sliders like that?

I've been looking online, but I can't really find too many parts that look like what I want. I know there's also the 60mm faders that are offered in the Livid shop. Can somebody share their experiences with these?
