I picked up a pack of this one week ago:
It contains 4 different beers - 2 oatmeal stouts, 2 dark ales, 4 IPAs, and 4 original ales.
The oatmeal stout and dark ale are absolute winners. I always look up a beer's ratings on beeradvocate.com after I taste it, and was a bit surprised to see the oatmeal stout given a 100 score by the bros. Anyway, these beers are two of the better beers I've tried since I moved to Boston 4 months ago. The IPA and original ale are very, very good as well.
Very highly recommended - of all the variety packs I've tried, this one is probably my favorite so far. I believe I picked up this 12 pack for ~$15. Well worth it.
