I am guessing you both spend time on ridemonkey...one thing, don't fall into the ridemonkey purchasing rut. Its an expensive rut to live in.
The dropouts work with either. IT has a neat tensioner systems that mounts either. But in reality I would always use a TA with it

Frame ends up around 400$...you buy direct from Kyle. The owners are good people

Your best deal comes when you buy it with a fork. I bought it last year with a slider and the frame was basically free.
