Pain that you can't remove the BB30 without damaging it or spending loads on a fancy tool.
Is it press-fit? I'v just built a CX bike with a BB30 bottom bracket. it seems that some of them just hold the bearings in place with a circlip. Mine doesnt, it needed the bearings pressed in.
The good thing is that it's not very popular yet, so second-hand parts are super cheap. I got a decent crank from ebay for £23 any other type of bottom bracket and it would have cost nearer £100
