So I am looking for a 26.6mm Seat post for my not single speed, So who makes them?

I am hoping to keep it to less then $50 preferred a 2 bold zero set back in black but you know what they say about beggars and choosers.

I only found one by Origin8 on e-bay but its 400 mm long and silver. I was hoping you guys might have an idea were I can find one.

Thanks in advance.
