Only a couple of suggestions;
Since short-legged riders fit LWB bikes better, be especially observant of seat height before you reach for the plastic. The Agio, is a good example. If you can't sit comfortably, and have at least one leg flat-footed (while the bike is perfectly vertical) then reconsider your choices. The numbers are not consistant, nor reliable, but if your below about 5' 7", then limit your search to 21" maximum seat heights. The Agio is closer to 25", I believe.
I have little knowledge, but have repeadedly heard that some untriangulated chain stays can be problematic when towing trailers. So, if you decide to tow, then hound the owners of mono stay bikes, to get an idea of which rigs work best for such applications.
Having never owned a Burley, I can't be of much help. However, I can say, that Burleys have been considered upper quality machines, with a respectable following. That said, I can't see you making a serious mistake, especially if you can score a decent discount. You can always sell it, if it doesn't suit you, and lose little $ in the process.
