You don’t need anything bigger than 2 Megapixel unfortunatly you won’t be able to find one because of the free market society we live in…lol
I would suggest a Canon A410 it’s a 3 Megapixel and it’s $119 and Walmart right now.
I use this Camera and it takes Better pictures than most of the bigger Megapixel camera’s that we are being scammed into buying more Megapixels does not mean better pictures and a lot of the time they are much WORSE.
I still print a lot of 8×10’s with my 2 megapixel camera.
It’s tough to beat Canon optics they dominate this segment of the market going away.
Good Luck.
