It's official - I have placed an order with a local music shop for two NX55p's. For the price ($650 each) it seems to be the best choice out there for my one-man-band gigging needs. It is supposed to have excellent sound, great bass response for a 12" speaker, good build quality, it can get rather loud, and it is one of the lighter units in its class. For really small jobs (such as those in private homes) I may just use my Motion Sound; at large gigs it will probably find use as a monitor for myself and any singers. Once again, thanks everyone for all the help.
