We have one of these, and like you Silvo we paid a bit more than that price as well :'(
They are great little cameras, have tested it on the bike and the Disco, one little problem I had last weekend was I accidently set it to still photo and got over 5000 photos instead of 4hrs of video
You view anything unless it's conected to a laptop, so you can't test it before you set it, not a big deal, just got to be careful before you turn it on and make sure it's set to video.
