Researching for Sue, Jake and Doug, in the AS world, right now, I only see 2 real contenders, though there are a ton of runners up:
Best bang for your buck is the Kumho Ecsta 4X at $101/tire (215/45-17) - $50 rebate = $88.5/tire!!! and it should be half decent in the snow.

The Continental ExtremeContact DWS for $117/tire. I think MattR and others have touted with probably a little better snow and dry performance and slightly longer life than the Kumho.
