MECA is relatively new but quite popular, still growing. Uses the same 'mike' as USACi for SPL (I think IASCA was thinking about going that direction but backed off). Their SQL is SQ first and foremost with minimal install points (street x?). IASCA and USACi have the pedigree MECA is a bit of a stepchild but in business you never know who will come out on top (usually the one with the lowest price). I wish IASCA held events in my part of the planet.
