I've got one and I like it... I don't use it as often as you do, probably. It being plastic, it is more prone to damage, but I'm usually pretty careful. I keep it in my back pocket when recording and keep it in a plastic bag when not in use. Sorry to hear yours is not working. I agree that the 12V really improves the sound, plus I like the smaller size.
I suspect if you asked it's not inconceivable that one of the wizards on here could do you up a 12V box. Most people don't like it because it uses that weird battery, but I don't mind that either.
