I understand that a dslr camera is highly suggested, but i dont plan to pay that much money (no more than $300) for one of those kind of cameras just yet.Would the samsung nv20 be a good choice of a camera?

One of my favourite hobby is photography. I just started to take photos since 2005. I use a samsung GX1. It gives quality picture(from my opinion).
Now I want to buy a DSLR. I’ve seen lots of camera form various brands but confused…… please give some advice.
