I'm shopping for an action cam, but the Go Pros are pricy. These are much more affordable at $69.00 and $119.00. Resolution is 5.1 mp. One is 1.7" lcd display and the other is 2.0" display w touchscreen. Yes, you can get the bike and helmet mounts separate. Is this a case of "you get what you pay for" or is it a good value?
