i was wanting to know if the VX200 will shoot in the 24p mode
Nope.
Also, I think you must mean VX2000. That camera is several years old, and if it was used by an event or wedding videographer, the chances are that the heads don't have much life left in them. We estimate that, at the rate we shoot weddings, our VX2100s will last up to three years before the heads need replacing. Your camera is probably older than that already.
As for the look - you should really view some films shot with 24p and compare to those shot with 30i. Just because you're wanting to produce a movie doesn't necessarily mean that you want 24p. A realistic, documentary or CourtTV style might work better for some movies. Also, the difference is so subtle, that you may not even notice, thus making it less an issue, compared to finding a good deal on a camera.
