I haven't been into bikes that long, but I've fallen in love with 3 speeds. I keep looking at all these new iterations of the 3 speed, but there's only a couple of them that get it right in my opinion, and the ones that do cost over a grand. That's way too rich for my blood.
I got a good deal on an old 3 speed from CL, but it's a little small for me and I don't even know for sure who made it. So I'm still on a hunt for my perfect 3 speed just like you. I might have a chance to find one this weekend though. So if I find one you will see a post with lots of !!!!!! and lots of pictures. Good luck and I hope I see a similar post from you in the near future.
