New BB30/PF30 bottom bracket

After a bit of advice really, my bike originally came BB30, but after having a creak I took my bike into my LBS, they replaced by bottom bracket with a cheap FSA PF30 unit without telling me of the change. This change was made in February, one of the bearings has already given up the ghost after just under 550miles, so to say I'm disappointed is an understatement. My frame has an area for muck to come in where the internally routed cables exit the frame, so ideally any replacement would be relatively well sealed, their was a bit of grime around the bearings when I took them out.

Has anyone got a particular BB30 or PF30 bottom bracket they can recommend? I'm not looking at spending a fortune like the Chris King unit I've seen for £165.

I know their are conversion kits to turn a BB30 shell to work with Shimano Hollowtech that seem durable from the customer reviews, but don't want to go through the cost of replacing my chainset as well.
