I bought this but ended up going a different direction. It is brand new and I am selling it for the price I paid. $80 Shipped.

The tube and head of the Thomson Elite seatpost are integral-machined from one single piece of high strength 7000 series aluminum. The head is not pressed or bonded in. This allows for superior strength and minimum weight, allowing higher strength at low weights.
