I need a 26" suspension fork for an old kona frame. Disc or canti mounts will work. 

Air spring would be ideal because a light weight person will be using it but I'll consider others if they are in good working order.

I can pay cash but I also have lots of nice items to trade such as...

Race face Sixc carbon 785mm bar
Easton Haven 55mm stem
Lots of great tires, 26" and 29" maxxis, schwalbe, wtb, specialized
Hydro brakesets, elixir nine carbon, formula rx, hayes stroker trail (fresh rebuild, new pads). 
Got a lot of other stuff too, just lemme know what you're after

EDIT:
Thought of a few more things for my list of stuff to trade with. 
Steel disc CX fork from a traitor crusade
Zion rigid disc 29er fork
FSA cranks (new) with used BB of the cheap and bombproof variety
SLX 10 Speed derailleur
Thule fork mount tray
Free hub bodies for Hope pro 2 evo one standard, one for xx1
New Clement MXP 700x33 tires, one mounted but not used, one still in retail packaging.
Juicy 5 brakes

1-1/8th, threadless so not that old. Not sure on the steerer but it's a small frame so I don't think that will be an issue. 

Should probably also mention that 80mm travel would be ideal and 100mm would be the max.
