What would be your chose and advice?

I'm between buying a Nikon D3200 or a Pentax K50, I can buy both for the same price but I don't know witch would be a better buy

Each have their advantages and either one would be a good investment for you. Maybe this tool will help.

Got to love that weather sealed body on the Pentax K-50.

K50 because of weather & dust proof body and it's got image stabilization built into the camera so you get IS with all lenses. With Nikon you only get VR on specific lenses.
Otherwise they both have very similar specs.

You mean you can't choose between a medium level DSLR that meters with MF lenses, has in-body anti-shake, a pentaprism viewfinder and weather-sealing - and is made by the company that built the first Japanese SLR, the first autofocus SLR, and pioneered the instant-return mirror and TTL metering - and an entry-level model with an idiot magnet on the front.

Are you serious?

My chose would be an Pentax K-50 in shocking pink!

Pentax K50 cuz it has weather and dust proof body.
