So i'm currently shooting with a bridge camera. I would like to upgrade (again) to a DSLR. I had a Sony A230 I loved but it had a major accident, the shutter broke. I'm looking for something I could get a good deal on (most likely used). I'm not really picky on a brand right now either. I do a lot of outdoor photography, (waterfalls, animals,ect) and a lot of portraits. Seem to be making most of my money lately on seinor pictures. What would you reccomend?
