I have one of the new 3.0 MP Stealths (got if for free because my 1.3 MP sucked so bad). Not much happier with the 3.0, but haven't used it much. One thin I did notice, is that the solar panel will not charge the batteries in the new 3.0!!! don't ask me why - but I think good ole Stealth wants to sewll a lot of those battery kits - one big scam!!!
