Full Suspension MTB or just a new Frame Currently I have a hard tail that I love, but I know that as I get more into mountain biking I'm probably going to want to upgrade. But I'm still pretty new to the trails. I'm wondering which you all think (this question is opinion based) I should buy: a Full suspension bike or just a full suspension frame, using the old components I have. I have a Diamondback hardtail, so yeah it's pretty cheap but I like what I have and the fork seems pretty good as far as I'm concerned. Also, I'm trying to keep a low budget (like under $1000)
I think first you should read up on the price point people recommend staying with a hard tail. Below that figure (about $US2000 depending who you speak to) Soft tails are heavy with poor rear suspension performance. 

Almost always, the most economic way to upgrade is to sell the current bike and buy a second hand one. The BD (if its the bike I am thinking of $500ish price point) does not have components worth putting onto a a ST frame worth riding. 

If you are new to MTB, and enjoy the bike you have, stick with the bike you have and start saving until you get a bank balance that lets you truly upgrade - not just a sideways or downwards shift. Riding a HT needs skills that you can get away with not having on a ST. These skills make you a better rider and a HT is the best way to learn them. Don't upgrade till you are sure its the bike limiting you riding - most riders get much more improvement for a lot less by upgrading themselves rather than the bike - get some training - a coaching session or four, read mags and books, or watch few MTB coaching videos.
