If your price range is $100-200 then the sky is the limit in terms of choice of camera. You'd need to check an aperture chart but set a folder on f16 and using a hyperfocal length of say 15 feet everything will be in focus from about 7.5 feet to infinity or if it is street/people shots then f11 will give you a massive range of distance and so becomes point and shoot
