I would not suggest and HD, mostly for one reason:
It is not definate that either HD or Blueray are going to make is as the standard media format.
Also If you are new to filmmaking you might want to get a cheaper camera than something like a GL2. When I was in college I bought a Canon Optura Xi, which is kinda hard to find these days. They allow for a lot of manual control, which keeping the more complex stuff simplified. It is a great camera and is really good for someone who is new to filmmaking. It goes for less than $1000 these days and it will last you until you are ready for a better camera. It is a mini dv but it does really great animorphic 16:9 shooting.
I still use mine. and I can definatly say it is worth the money. Evnetually you would want to save up money and get a much nicer camera. I am going to be getting an XL2. I am skipping the HD for now because it is jsut not a viable format, and honestly it may not become one for home entertainment.
Since you are new and are wanting to experiment, get a cheap camera that gives manual control and then look into buying a good NLE. I got Vegas when I was in school for around $300, with academic discount. Just remember, when it comes to films. the camera is a very small part of the equation. If you need more info let me know.
