I know folks are interested in a Lefty fork
here is a used one for sale on craigslist in Austin:  (SOLD - LINK DELETED)
price seems high to me...but everything has a price.

If I were building a new 29er and lived near Austin, it would be worth a look.  Thanks for posting.

im using the same lefty on my ip-057, 2011/2012 100mm 29'er w/ XLR,  i picked it up on craigslist with a wheelset (stans ZRT arch rims / c-dale lefty hub front and dirt flea in the rear) for about $300 less than what this add is asking for. while i am a BIG lefty fan i think this price is a little high. remember, any lefty from 2005 up to 2012 you can remove the internals and upgrade them to the 2012 latest greatest. id ask the seller to come down a bit and if not is recommend you keep looking. dont give up hope though, Leftys are worth it.

Clicking on the link..it looks to be still for sale.
