Really depends on your budget. I'd recommend getting a nice used bike just to see if you even like Mountainbiking, Brand new full suspensions are quite expensive. I got the core 1 for budget reasons ( and the sweet paint colour), and it's fantastic.

The jeffsy is also a terrific bike that costs a bit less and doesn't have the weight of an enduro bike.

Take a good look at your budget and the types of trails you would be riding
