Man, I just bought the Vixia HF-10 a month or so ago. I started with the JVC Everio, which is a piece of shit. The HF-10 is as good a camera as you'll get without spending several thousand dollars. Not sure which NLE or computer you use; it works very well on Mac's as long as you have either iLife '08 or Final Cut Express / Final Cut Studio.
Picked it up at Best Buy w/ the performance guarantee for less than $1k...I don't do that bargain basement BS, and it was actually a better deal than B&H when you factor in the 4 years of accidental damage replacement coverage.
Get yourself another 16GB SDHC card, and you have an assload of recording time. I've been quite happy with it tracking my son's kart on a 1/4 mile asphalt oval from the grandstands. I limit the digital zoom to 40x, and even at that, it can be too much. Crystal clear optics, which is a Canon hallmark. Very very clean video, and the 60i/30p/24p modes allow you to have some fun with it.
You'll freak at how small and light these damn things are anymore.
Now, have you ever used Canon HV20/30?
I am what they call "old school". I feel the uality is related to the medium. Tape being the medium so far fullfilled the quality. AVCHD is kind of new kid of the block and I am wondering about the artifacts etc.
As of my computers, I have about as many as Shane has cars.
Top of the line:
Q9300-based 3.0 Ghz (Quad core, lightly overclocked);
E4700-based 3.6 Ghz (Duo core, quite overclocked);
E7200-based, 3.8 Ghz (Duo Core, quite overclocked);
As you know, I can run OS X on any of them. I am not sure Final Cut port is functional though, I have to double-check.
So far Sony Vegas Pro and Uled VideoStudio worked out fine for me.
Still.. the dilemma..hard to forget about the tape..
