I just see cheap Sigma 10-20mm f/3.5 DC HSM on the market. Is it worthwhile to get it?

Only lens I have now is the 17-70mm, would love to get the 8-16mm though, maybe the 10-20mm is a good compromise?

Any comments?

I have the f/4-5.6 version and it's supposed to be a bit better optically than the f/3.5. I can tell you it's a decent lens but at 10 mm you will see quite a bit of distortion on the edges.

It's not better, no lens manufacturer makes a later iteration of a lens worse than its predecessor. They have slightly different strengths, imaging resource's comments on the newer lens compared to the older are as follows:

The original Sigma ultrawide-angle zoom still holds its own, being slightly sharper at the telephoto end of its spectrum than the newer version. CA is also slightly better in the older version, though the newer version improves on corner shading and distortion. The new version uses 82mm filters instead of 77mm, but offers the constant ƒ/3.5 aperture.

All UWA lenses have some weaknesses on the corners and edges, but the newer version is better than the older version in this respect. That being said, I don't think anyone should be disappointed with either one.
