Yeah, in your situation, CD, I'd opt for the 35. Great lens. Strangely enough, nobody mentioned the 18-55 or the 18-105 lens for landscapes! The 18mm focal length will give you a wider FOV for landscapes. It doesn't have the light gathering ability of the f1.8 lenses, but you did say landscape, and I don't know many people who take landscape shots at night.
While I'm at it here, where are you situated on the planet? Prices vary all over the world, so it would be nice to know where you are, so we could give you an idea of the prices of gear where you live.
I was going to mention it, but figured the OP has the 18-55 that came with his D5200, unless he bought the body only. But yes, the 18-55 is a great lens for landscape, and if if it's in low light just stick in on a tripod.
