DSLR

I'm thinking to have a DSLR camera...
plan to buy it but i don't know which model should i buy...
haiix...
should i buy the cheapest one...
what in my mind is this camera not only can use for one year....
it might have 2-3 years live...
if i buy a cheapest price one i will feel regretted...
buy expensive one i don't have enough money...
because it's really a luxury item for me...
what should i do?!
put this plan aside or continue thinking of it...
i really hope i can have one and bring it to any places where i am...
i really hope that the camera got your picture...
i want the feel of satisfaction when see the picture taken by me...
i want...
but it's not affordable for me...
how how how...
who can tell me what should i do?!!!!!
