I have been a big IPA fan of late and LOVE the Lagunista's Little Sumpin' Sumpin' ale, great name and a hearty IPS too, in fact, all their IPA's are excellent, hoppy but not too hoppy.
For a plain 'beer' you can't beat Blue Point Toasted Lager, for what it is it's expensive (usually ~$10/6) but it's just such a good lager and I have a great local seafood restaurant that has it on tap here so that's always a plus!
Most of the Colorado breweries I've tried are solid, Fat Tire seems to be the standard by which all other CO breweries are judged, but their are many good one from there.
We here in Tampa used to have Cigar City right in town but they have moved, the Jai Alai IPA is really good from them.
Just a few to ad to the list but if you can find the Lagunista's try them! I like all their beers that I've tried (had like 5-6 so a few!)
