I'm a private party. I've just been buying cameras off ebay here and there trying to figure out what I wanted to do. I have 11 cameras going now.
I'm sure there's better cameras out there but what kind of money are we talking about. Whether its cameras, speakers, amps, ect. the law of diminishing return usually kicks in and you have to make a realistic decision. I got the 7410B off eBay for $15.99 +8.99 shipping. I think for the money the picture is very good. I also like the size of these. I would imagine to get pro quality in a .91" W x 1.125" H x 3.94" D would be very expensive. Don't get me wrong I would love to have the pro stuff it just doesn't make sense when these do what I want.
