1. do you really need a DSLR? its quite hard to know for sure. most acquire one, then left it behind because it is just too bulky for comfort. in short, not everyone is an enthusiast.
2. granting you want one, choose one brand. do not cross brands as kits are quite expensive. the thing is camera bodies come and go. but buy the best lens your money can buy.
3. in photography, "talent" comes a long way. you may have the most expensive kits, updated wares, etc. but your composition "sucks" the photos you take may not make an impact.
4. that said, photography is quite an expensive hobby. it takes money to travel and shoot at places, people, and events.

As to your query a Nikon D500/D700 or a Canon 600D/650D is nice to have. 60D if you the moolah.
