I would buy if it the price was nice. Defender is one of the best cabinets around. Well built, lightweight, nice viewing angle on the monitor, monitor sits on a shelf so it is easy to service, and the control panel is a flat rectangle of wood. It is plywood not particle board (so it doesn't fall apart or swell up like Atari cabs do).
Defender is pretty much the easiest 19" cabinet in the world to deal with.
