Canon HD Camcorder - HF, HG, HV???

Hey Guys -

There are a lot of threads recommending all of these camcorders. I'm trying to figure out what would be my best choice. Any of them fall into my price range. It's confusing to me as they all seem to be priced similarly.

I'm looking to use this primarily for filming wakeboarding. I will be doing some editing as well (learning). I have a lot of external hard drive space, if it matters (1TB).

I'd like to be able to sustain the best video quality possible while transferring to my computer.

I'm hoping to get a waterproof case for this as well.

Let me know if there is more info that would be helpful to know.

Thanks a lot, and sorry if this is a repetitive post. I'm new to this area of the site.
