I disagree on the red/puy similarity arguement as puy hold their shape much better, and have a more earthy taste. That said puy are very expensive. I just buy 5kg bags to get good deals!
get down Khans Bargain in Peckham Rye: they do industrial amounts of all sorts of beans, pulses, lentils and dhal. Think 5kg of chana dal cost me under a tenner the other day!
