Thank you all for your advice and input!
It looks like I'm going with the dual tap tower. It just makes more sense.
DCullender I too live in the Richmond area, and I noticed that on the Corks and Kegs website, there seems to be a limit on the variety of sixtels with there tremendous keg menu. And I do notice that some are really expensive. Especially the ones I'd like to get.
But that's just a sacrifice I'll just have to make.
Thanks again!
