Thanks for the suggestions. Now that it's been a few days, my new-bike lust has gone down a little...

I think I should spend a little more time on craigslist, just to price the market a little better. How about eBay these days? Has anyone had good luck with buying a bike from someone across the country recently? I think I was lucky when I bought my Bianchi because I bought it from someone in WI, and everything worked out well.
I generally ride to work 2-3 times a week (35 miles round trip), then maybe a 40-60 mile ride along with a 20-30 mile ride on the weekends. I certainly don't race, but I'm thinking a smaller group ride might help in terms of pushing me a little more while teaching me about riding in a group. While I no longer am trying to reach 60MPH on a bike, I do like to find a good pace that eats up the miles. I'm not sure how that would classify me.
