How about K330?
D Major, K. 311. It's a wonderful one!
K. 311 is indeed wonderful, but I have to say any desire to learn it has been quashed by hearing someone at university playing it terribly on multiple occasions... very, very fast with too much pedal and missing notes, obviously no respect for the composer (and then went on to play Gaspard... I can't say I have much respect for his teacher

) I also love K. 330 and do intend to learn it eventually, but I thought that since I have learned K. 332 the ones I listed might have more "educational" value for me at this time. I was leaning towards K. 284, but I'm becoming increasingly persuaded by Clementi op. 40 no. 3... hmm...
EDIT: And now I'm listening to K. 330 after a long while and I'm even more confused!

I'm also not working with a teacher at the moment, so am a little nervous about trying things which I might have trouble interpreting...
