I have not but for under $20 (with shipping) It may be worth a shot. Iv'e been looking on CL for a while now for a new to me saddle for my old bike and there's virtually nothing. I checked the Dallas/Fort Worth CL after I read your post and couldn't find anything there either.

I am considering trying this seat out myself because I just bought a new bike and don't want to spend too much on my soon to be fixie. I'm converting an old Diamondback Master TG into a DIY fixie on a serious budget.

If I end up getting it I will come back to this thread and let you know my opinion.
