Hi Dirtroads,
Flounder is steering you so right it's not fair! he's spot on.
I have moved from a $6,000 Carbon Ibis Mojo, to a $700 Haro Mary 1x9 steel 29er hardtail, and I cannot tell you I'm having any less fun! I sold the expensive bike when my son was born and when I started a new business, and I have not looked back. Now I ride the trails hard, and guess what; my bike rack for the baby seat is still on there for when I take the little dude on the rail trail.
Point is, buy what you need, not as much what you want; and don't get lost in the newest fads. A solid bike is all you need.
