We have 6 of the little cheapo Muddy cams out. Great bang for the buck, and the battery life on cheapo Amazon AA batteries is amazing. Some of these have been out for 10 months on the original batteries, and still taking pics like champs.
Lol at Blackstone, and yes I do have about 25 of them out and every now and then one will act up but for $34 for a 14 megapixel camera you will not beat it and the batterys last forever.
