What's your budget? I would go black flash if you can afford it. My dlc covert black 60 has over30,000 pics on the same set of alkaline battery's since July and I paid 200 to my door online for it. They have cams in the 115-150 range that are red flash but work just as well... Mp6 and red 40 What ever you do go over and look at the reviews at chasingame before you buy. Good luck.
Moultrie M80 going strong for 2 yrs and gets around 20000-30000 pictures per set of batteries depending on if I use the video part in there too.
I bought 2 of them this year and love them. Battery life is incredible. I put them out in July and haven't changed the batteries yet with thousands of pics taken.
