If you want "nice" video (and by that I'm assuming you mean "sharp and clear") you will have to pay for it. I don't know what kind of vid cam you looked at for $150, but my advice is to save up and get a good one. I just bought a Sony the other day and although it cost me, the quality is excellent.
If you have a look at places like www.flightlevel350.com
you'll see a wide variety of videos, quality-wise - the crappy-looking ones are ones that were taken with cheap cameras.
So...it comes down to what you want and what you'll be satisfied with, quality-wise.
