I gotta agree that it's a little high... I've never paid over $250 for any of my cabs, but I usually only buy somewhat broken and cheap stuff (I really have to limit what I buy now since I have almost no room anymore :P ). I guess for a starter cab, it's not bad since it's fully working, and maybe in nice shape, but really, if you're wanting to learn, you'll learn a lot more fixing up a beat up/non working machine.
