Yep, that's a T47 30mm internal BB. To be fair, there are cheaper alternatives to C-Bear in pretty much every department. Wheels Manufacturing or White Industries T47 BBs are 99 dorrah, for example. Not cheap, but not that much in the great grand scheme of things. Let's face it, if you're even thinking about a T47 BB then it means you're buying an artisinal bespoke frame, which is not going to be a budget option.

Dunno. Depends on how many you chew through I guess. PF30 in my experience has been pretty bomb proof - three bikes with it, all off road types, two of them all weather, £16 investment in one replacement BB in cumulative 3500 miles. Hammering the fucker out wasn't very nice though I have to admit.
But yeah if you are using that type of BB you are using spendy cranks too so what's another couple of beer vouchers.
