Mate, I've got no experience with the camera you mention, but I did just purchase a cheap action cam myself for $100 delivered off ebay. I did a fair bit of Internet research before the purchase. There are quiete a few decent looking cams in that bracket now, but I'm hoping this one is the pick of the bunch. I choose it after seeing a review online from a guy who reviews a lot of these cheaper action cams. He seem's to think its the best one out there atm for the money. Here's the link to the review, the review also contains links to eBay.

See what ya think.

Hey Piros I thought that the GoPro had a fish eye lens , I gotta admit Im a bit over it and I am now trying to flatten all my videos (thank you motion 5).

Greg C , the Go-Pro black has 3 settings , narrow , wide & extra wide , plus all the new Go-pros have a Flat port over the lens which lets them focus underwater.

t457118, This was shot on the white and looks pretty nice shot at 1080 x 25p , parts of it are slowed down , even imovie can help smooth this out , just don't slow it down too much. 25p & 50p is fames per second so yes it will be smoother shooting 50 fps when you slow it down in post production but it takes us twice as much space on your card and punishes your computer.

Keep it simple and just shoot alot 2.08 - 2.30 is slowed down and looks pretty smooth to me (shot at 25p)
