I am considering the purchase of a cajon,and would value any comments,based on personal experience,from other "'Catters" : I have,so far,looked at one make from Spain,and two from Germany,and am torn between the idea of a "two-in-one" cajon,ie one with two playing surfaces,(one with snares and the other without), or a single-purpose snared cajon with " add-on" bits like the "Heck Stick" and "Side Kick". Any thoughts ??
