Gotta agree with NRDK and Kiltie - lovely area, but as for being a hub - not really feasible. The town of Oban is lovely, the local Uiske Beatha is wonderfully smooth drop, and some friends own a nice little chalet complex just outside, within reach of some of the best walking scenery I've ever seen. No way can it be called a major centre of population, though.
But North Connel has some horribly drastic cumulogranite around...
