I see the dealer I bought my bike from is selling their 2011 Quicks for $30 to $50 off of list (though they don't have all sizes anymore). Not a huge amount off but it puts the Quick 4 at $599, Quick 5 at $519 and the Quick 6 at $399. If any of these 2011s are around in the spring you could get a pretty good deal, depending on the dealer.

Another option is to buy a bike and get a trainer to ride it on in the winter. What do you do for exercise in the winter?

That said, what Velo said makes a lot of sense.
