29" ISIS w/ or w/o schlumpf

I’d like to buy a heavier duty 29" for commuting around my campus. Without a schlumpf I’m looking to spend less than $300. With one I’m looking for something less than $1500. Alternatively if you have a 22.2mm seat post 300 mm or longer that would be a good substitute for the time being, as my current 9er is killing my knees from too short of a post.

UDC UK has longer 22.2 posts in stock. Based on some friend’s experience getting items from there to the US, shipping shouldn’t be too bad.

A new uni is always cool, but cheap for now may be a good option.

Wheelset and frame has been found, thanks all.
