GoPro Hero 3 replacement skeleton

[tjdixon911]

I need a replacement skeleton for my hero 3, does anyone have experience of the cheap eBay ones or should I stick with the original?

Main use is strapped to my chest on my mountain bike...

Thanks,

Tom

I don't know how cheap the eBay ones you are looking at are, but I have tried some 3D printed ones and they weren't great.
