Mmm, well thats a great price but and I would say, this is a big but the Zi8 which Im guessing (Im not the in the States) retails for about $180, is a much better buy.
In the UK, although the Zi6 can be had pretty cheaply with todays exchange rate about $95 when I looked into it, decided that the Zi8 was a much better buy (todays exchange rate, I got it for $180).
Many reviewers seemed to agree that the Zi8 fixed a lot of the shortcomings of the Zi6.
In terms of quality, the more critical reviewers said about the Zi6 rather like most similar offerings that one may as well stick with a mobile phone that can take video. Certainly, the Zi8 is much better in this respect and handles low light conditions better (although all of these small cams arent great in these conditions).
As bokdol says theres no image stabilisation with the Zi6 there is in the Zi8, but like similar cameras, this is a digital stabiliser, which means its better than nothing but not great. Dont forget that a fair bit of editing software as stabiliser tools and youre always going to be best off using a triposd (the gorillapod is ACE).
As he also said, check out the various footage online but I would have a look at
http://chris.pirillo.com/kodak-zi8-review/ Mr Pirillo wasnt that keen on the Zi6, but had a very different take on the Zi8.
The Zi8 has an input for external mic, which is very handy this might not be the case for you, but do a web search for some examples to show what a difference this can make. Im pretty sure that the Zi8 is the one offering that has this and its made pro users interested in it.
I do think thats a good price you found and it will be something fun to play around with, but if you think youre going to do quite a bit of video, I feel that could be a false economy getting the Zi6. Im not one who encourages spending more money to get something better for the sake of getting something better, but do really think that that its work spending the extra money to get the Zi8 because all well as better quality, it will last you longer.
Briefly going to your questions about other pocket cam suggestions, I would have a look at the various footage online however, I did a lot of research myself a couple of months ago and thought that the Zi8 came off as the market leader currently.
