WTB or WTT for Wideangle 14mm etc.

[LSUConnMan]

I'm hoping to find a Sigma or Tamron 14mm since I know I won't use it enough to justify the price of the Canon. But I'll settle for a Canon 14mm I or II if need be. I'd also be interested in a 17mm or a 20mm wideangle as well.

If someone's interested in a trade, I have a 24-70L I'll happily part with.

I have a Sigma 20mm f/1.8 EX DG if you are still interested.
