Not a clue, but I have a high regard for them. They make a whole range, from very pedestrian, to very high performance. I've had quite a lot of success in calling manufacturers, explaining what I need and seeing if they'll recommend someone. Very often they'll be willing to supply a handful of parts as samples, or even break their rules and accept a small order. This has only worked for me if I call them directly. Email generally doesn't work. Obviously being as nice as possible has a big influence as well.
