@dfoster85 - Assuming you're an adult, yes, an internist would be a great choice for a primary care doctor. My primary care doctor is an internist and I've been really happy with her.
There's nothing wrong with a general practice doctor, of course. That's a great way to go if you have kids and want one doctor to see the whole family. But an internist will have focused his or her whole training on adults, while a general or family practitioner will have studied a lot of other areas as well (e.g., pediatrics). I would assume that leaves less time for adult diseases. (But that's just training--a really smart, up-to-date family practice doc is always going to know more than am internist who graduated at the bottom of their class and hates to read journal articles.)
