All reply is really help me to figue out many thing. Thank you a lot , I think I will wait till the end of October because I will graduate frim bachelor degree and may be new DSLR is a gift

. I think I will consider the option between D600 that have a rumor , 5D2 and D5100. All the answer from your guy gave me a second thought about did I really wanna invest a budget in camera just for my fav hobbie. Well , I think that would be good if I buy DSLR that will be my last one I have to think really carefully about my second move.
Thank you all your guys
