choose between these 2?

[dash's_dad]

Sigma AF18-200mm F3.5-5.6 DC (EOS)
and
Sigma 18-200mm f/3.5-6.3 DC OS Lens - Canon?

Aside from the $150 price difference and the aperature, is there much to choose between these 2 lenses?

I think I've been swayed to the Sigma in an effort to save close to $200, but if anyone has any opinions on the Sigma vs. Canon version, I'd love to hear them.

I believe that the only major difference between them would be the OS (Optical Stabilization). This is pretty nice to have, especially when you are shooting closer to the 200mm end than the 18mm end. The difference in aperture would be negated (I think) by having the OS. I would spend the money and get the one with the OS for sure.

check out the 18-250, it's rated a nine here http://www.slrgear.com/reviews/index.php which is better than the canon and much better than the other 2 and around $550
