I am a big fan of Haydn's string quartets (at least the ones I've heard), and over time, I hope to get them all on record. I was wondering if anyone had suggestions for recordings that are particulary good. I plan to make it a mid to long term process, so it doesn't matter if you can only recommend a few. There seems to be only one complete set existing anyway, and it's gotten mixed reviews.
