What deal should i go for. Nikon D5100?

So im planning to get the nikon d5100 soon and im torn between two deals.

Deal 1
buy camera body for €529.99 and a seperate lens for €379.99 so thats €910.the lense is a Sigma 18-200mm F:3.5-6.3 OS (Mark 11)

Deal 2
buy the camera body that includes a 18-55mm lens.which is €649.99 then buy a seperate lense that costs 249.99.the lens is Nikon 55-200mm F4-5.6 G VR AF-S DX. making it €900.

im leaning towards deal 1 because im too lazy to keep swapping the lenses all the time.but at the same time im not sure because in deal 1 its a sigma lens and in deal 2 its a nikon lens.being a nikon camera i kinda want to get the nikon lens.

does the brand of the lense matter? please help.

thanks.

Which is better. Olympus E-PM1 (14-42mm lens) OR Nikon d3000 (18-55mm lens)?

I am very interested in beginning photography as a hobby. I've had multiple "point and shoot" cameras in the past that I played around on and used for trips and events. But now I want to get into professional photography (or as professional as I can get)… But I wanted to know which one would better suit me. I like the Olympus because its small and easy to take anywhere but still takes good pictures. But I want to get out of the point and shoot rhelm and take pictures "right".So that is why I was considering the Nikon. They are both about the same price (the Nikon is a little bit more). I would GREATLY appriciate it if someone with experience could help me out in choosing the best camera for me.

Upgrading from 35mm film to DSLR?

Hey! I've been shooting 35mm since about june and i think i'm ready to upgrade to dslr in time for christmas. I've been looking at several different cameras from beginner cameras such as the Nikon D5000, to mid-Level's such as the Nikon D200. What differences are there regarding exposure settings, menu navigation, etc. Thank you so much! And is the D200 full frame?
Added (1). D200's go really cheap now, too.
