The issue with competition bells is that most manufacturers I've seen go to 32 kg only. The AKC has bells that go up higher (maybe 64 kg?) but they're expensive as all hell.
It depends on your goals. If you're looking to do real long sets, I'd save up for the comp. bells. I've got a pair of 16kg, 24kg and 32 kg that I both saved for and spent the winnings from a rather stupid, but fortunate roulette bet.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
