Have a chance to pick up a Canon HF10 at a very attractive price ($400). I've been looking at the HF20 and HFS10 and am wondering if the HF10 is "good enough" given the price. HF 10 - 2.07 Megapixels (1920x1440) - 17 Mbps max HF 20 - 2.99 Megapixels (2304x1296) - 24 Mbps max (around $800) HFS10 - 6.01 Megapixels (3264x1840) - 24 Mbps max (around $1000) Isn't 1920x1080 considered "full HD" - it seems all three would be capable of that. Also, would the 17 vs. 24 Mbps be that noticeable? I'm after good vacation videos, band concerts, swim meets, etc... not a professional videographer. Opinions? Suggestions?
