VST Vocals

I’m looking for some advice and/or suggestions about VST Vocals. I would like to have some basic solo and choral sounds available to me when I’m composing. They don’t need to be particularly extensive, I just want to be able to hear approximations of what the vocals would sound like in the context of the overall arrangement. Does anyone here do stuff like this and have some ideas I could follow? Thanks.

Probably a little late to respond, but…

I’ve been looking for something similar, and finally came across an excellent sound library for Kontakt called Vocalise:

It’s $100, but totally worth it, imo. Lots of flexibility in what you can do, and the actual vocal samples are just beautiful. Here’s something I quickly put together in a few evenings with it:

Never too late! Thanks for the input, I’ll check it out.
