Vibration

If I have a vibration noticeable at 2000 rpms and up, would you think balance problem or a miss in the engine......It does it in nuetral as well...not just driving...thanks for any input offered.

At first I thought about the driveshaft but then I noticed that I can sit in my driveway and bring the rpm's up and still feel the vibe. I also just converted the car to a 5-speed and was thinking of maybe the flywheel not balanced very well. So I was thinking either Balance is off or I've got a miss. Whatcha think?
