If you don't mind a camera with internet access for beginner level photos a pixel 3 or iPhone 6 can be found for around that price and both come with unlimited google photos backups.
A gopro is a good option I know people who found broken ones online and had gopro warranty them.
Otherwise see if any photography people have old cameras they don't use. I bought a nikon d2x from bh about 3 years ago for around 150 used which came with a basic lens. However this usually ends in buying several lenses and a new camera.
