I like the Goodyear Eagle F1 A/S's. Yes, they get noisy after a while but for overall performance, wear & cost they're hard to beat. The perform extremely well in rain & not too bad in snow.
As to online vs. local tire dealer: go to Tirerack, figure out your total cost including shipping, then ask around & see how much they'll be to mount & balance. Once you get a good final number on how much it'll really cost try pricing the same tire at a local dealer. Sometimes (certainly not always!) the cost difference between the 2 is negligible.
