Agreed... also they're a pain in the neck to use properly! I have the Sigma and still find myself ending up with vast amounts of nothing (and/or my own feet) in my UWA pics, even when trying to force perspectives... but they're getting betterUltra wide lenses are not cheap either, the Sigma 10-20 is about as cheap as it gets(although a very good lens from most accounts) at around 400 euro.
