If you need a weatherproof camera there are some good deals on older (but still pretty recent) Pentax cameras like the K-5, K-5 II, and K-5 IIs (all 16MP). They are a less dominant brand and not the king of fast sports shooting (although not bad IMO) but if you like to hike/ski/bike to remote locations and shoot in harsh environments like I do they are great for that and give good IQ at a good price.
For any camera realize you are buying into a system. So make sure the lenses that suit the kind of shooting you want to do are available and affordable. For nature, landscape, and adventure I really like this system.
