If you are looking for a good seatpost, check out eBay for a Suntour XC Pro, or Superbe if you want the shorter road version. The XC Pro has the best seat adjustment I've found, I think it is called micro adjust, you can literally move the nose up or down by fractions of a mm. I bought one as new for about $25. They are long ~ 300 mm, but light enough and nicely finished. If you don't like it that long you can always cut it shorter.
