Hey anyone know what I should use for a tipi liner?

I have an 8 man Kifaru w/o liner. I couldn't justify the cost at the time and don't really need a liner often, but it would be nice sometimes.

I'm guessing light color or even white, light weight as possible, breathable and probably dwr?

That sound right?

Now where to buy that w/o breaking the bank...

Any ideas?
