Can anyone suggest any good drill bits, various sizes.

In the past I've bought Sutton / Frost, but they're getting so damn expensive. I always break the small ones and end up with 50 gazillion big ones. I'm wondering if it's worth me buying some cheap chinese titanium/uranium/can't be busted/super assed tough as guts ones off eBay.

Or am I wasting my money?

What about drill bit sharpeners? They worth getting or do they just stuff up?
