Full suspension bikes are not worth buying under the $1500 price range because their components are usually very lacking.
If you really want a decent full suspension bike, you need to open your wallet more. OR get a hardtail. It's a noob's assumption that full suspension bikes are always better. Bikeforums gets people coming on here all the time asking for bike advice, and often saying they want a 300-500 dollar full suspension bike. That's Xmart advertisement stuck in their head.
Hardtails are the best thing you can go with under $1000. There are many types of hardtails. They range from light Xc to Freeride to urban/dirt jumping.
Your best bet is to go to you local bike shop and ask them what they would recommend. There are bagillions of bikes out there. Only the more popular brands will be recommended to you on this forum.
I strongly suggest you thoroughly read this thread:
