In reply to Tall Clare:
DPR and the like are great for doing your research, and Ken Rockwell does provide a lot of opinion on lenses, camera bodies and the like. I think as long as you treat them all as opinions, rather than totally impartial fact, they all serve a purpose.
My opinion (rather than fact!) is that unless you're a pro shooter, it's far more about what camera (and lens combo) makes you feel like you want to get out and shoot more. Obsessing about sensor size, FPS rate, megapixels and dynamic range isn't going to lead to you getting out there and taking better pictures. One that feels comfortable in the hand, is the right weight and good enough build quality are more important. Think about whether you want a weather-sealed camera as well if you're planning to take it out.
The main decision point nowadays is whether to go mirrorless or conventional DSLR. Advantages and disadvantages to both - and proponents of each who will claim the other is pointless. Take a look at some side by side and have a play. If you can get to a proper camera shop (not many about, sadly), ask for some advice and get to use all of the cameras you can. If you have old Canon lenses then that may influence sticking with that brand, too.
The other thing you may be able to do - depending on what model you're after - is hire one for a weekend.
For what it's worth, alongside my DSLR, I still use my Mamiya film camera and sometimes even take it up into the mountains. It's a 4kg Rx67 Pro ii!
