Not only are new BB-7700 hard to find, they require more upkeep than a casual rider may want to endure. BB-5500 is a nice replacement for bikes still using Octalink V1 cranks, and the weight and drag are negligible for anyone not racing. Get over your disdain for 105, Tubby.
I use 105 bottom brackets for my cyclocross bikes. They are reasonably priced and give good performance at a reasonable weight. Bottom brackets seldom last 2 years for a cyclocross bike. For this cost I an swap them out before they fail and still get solid performance.
