Thelonius Monk - where to start?

[thrudge]

I've been listening to Monk in the pub and I'm impressed. I'd like to buy some of his stuff and want to start with a 'best of' or one of his classic albums. But I don't know which are the good recordings and which are the dull sounding re-re-releases.

Could somebody point me at a good quality recording along these lines, please?
