That Bruno Weil HIP set is great, and so are the incomplete Christopher Hogwood set, the Trevor Pinnock and Frans Brüggen sets with the "Sturm und Drang" symphonies and the Sigiswald Kuijken sets with the "Paris" symphonies.

Colin Davis' "big-band Haydn" sets with the "London" symphonies are my favourites in the non-HIP dept. Antál Doráti's complete non-HIP set is an early favourite of mine. The Freiburger Barockorchester and Pinnock made excellent recordings of symphonies 6-8. All in my opinion, of course
