13" keizer barrels?

So since I'm looking for 13x10 wheels and I have a set of 13x8 keizers I'm wondering if anyone has some used barrels to make mine 10's.Keizer wants $800 for 4 new ones which is way more than I think their worth and certainly more than I'm willing to spend. Mine have 18 mounting bolts and the muilti hole around the perimeter center section,my outer barrel is approx 2" so I'd need a 4 inch or I guess about a 6.5" inner barrel.

Two words.

Carbon fiber.

I know you know how to use it.

In reply to nocones:

Thanks for the vote of confidence but really what I know about composites can be written in a matchbook.I'm 100% positive I'd stand a better chance of spinning my own shell from aluminum than making a wheel with carbon,and the chances of me being successful with the aluminum is pretty damn small.

I used to use this guy but he's been to busy the past couple of years so i go else where now but in a pinch i'll get centers and shells and weld'em up my self. He might sell you some 10 inch shells and centers.

Well Keizer 1st quoted me $180ea for new barrels but now says $78ea.I'll just get a set of new barrels as it'll be about the same cost as a new set of steel wheels with half the weight.
