Bartok piano sonata - recommended recordings?

[fnork]

I´m playing it now and would love to hear some recommendations on good recordings. I´ve heard plenty of recordings of mixed quality so far, and very few that I´ve really enjoyed. Lang Lang bangs his way through the piece...Mei-ting Sun had a recording on his website a while ago which probably is the best I have heard so far. Zoltan Kocscis recorded it at least twice, and the early recording is not bad, but I much prefer his recordings of the concertos. The 2nd recording of the sonata that he did is rather special, and I don´t find it that interresting...

So, what other recordings can you all recommend to me?
