Newbie to the forum but I have managed to use the search button

What I'm after is a DSLR that has all of the following.
1) a screen that can flip around.
2) a remote control
3) preferably takes Sony memory (not 100% needed though)

I do a lot of fishing for large carp and I'm usually on my own to take photos. I need a camera that can take good night shots as a lot of my fish come in the dark hours. If you can picture it (excuse the pun)

I am in front of the camera on the tripod with a large fish in both hands, remote ready to trigger the camera. What I would like is the screen so I can see the shot before it's taken. The facility to take 2 or 3 at a time would be very useful.

Enough pixels to get good shots to A3 size.

I'll also be taking a lot of scenic shots of lakes and rivers. Being able to get a polarising lens would be great.

Sorry if this is a bit of a ramble but I'm looking to buy and i'm lost
