Looking at getting a camera to strap to my handle bars but no idea whats hot and what not, go pro hd hero 2 footage looks good but the 3 is out now so is that worth the extra money or are there better models out there for similar money?

No idea if this meets your requirements .. didn’t fully read it..

My son has just bought a gopro hero 3 silver. Great bit of kit.Wifi allows preview/remote use on a suitable mobile/tablet.3 is more compact than the 2. There is also the 3+ out now – better battery life and a few other things at the “black” level. Black gives faster frame rate if you’re going to do serious slow motion at 1080p. If it’s just action I would say the silver is fine and use the difference for mounts.

Have a look at the JVC XA2. Similar spec to a gopro silver but robust without the case and with a built in screen. It also has conventional tripod mounts on the bottom and side, providing masses of mounting options. Takes a full sized SD card too, so you can put a 128gig card in if you want. Really happy with mine.
