I should point out;that I don't dislike Joan Sutherland's singing;I just haven't been particularly moved by her singing,to date. This is partly because of here repertoire,which hasn't really appealed to me. But times move on,and your tastes developd,and I've often been tempted to explore some Donizetti. I think part of the problem is the sheer profusion of operas. He composed so many. Not being a wealthy man,I tend to concentrate on certain core areas,and unfortunately some composers get left out!! 
Having a recording without cuts does make sense,though. You can enjoy a score with cuts if the performance is particularly good;but if you're an intelligent music lover you obviously need to hear what's been left out. My shelf is groaning with the weight of multiple Mozart opera recordings (not many compared to some here,no doubt) so I don't think I'll be able to resist for very long!!
I need to know!!
I don't dislike Sutherland either, but, as I pointed out in an earlier post, she is not a singer who really "speaks" to me. I have very few recordings of hers, but I do have a lot of recordings of
bel canto operas, which of course include the operas of Donizetti.
I do have her recording of
La Fille du Regiment, which is delightful, though, even here, her mushy diction bothers me somewhat. Pavarotti is superb, even if his French isn't that good. I think it's one of his best recordings.
Other than that, the
bel canto operas I have are.
