Best C# windows forms custom listview control you know?

Hi Experts,

I'm about to write a C# app and was considering buying a package that has a good tested control for list views and I'm not sure it's worth it.  Maybe there's also a good free one.  I'd like something that can build a complicated UI with list views (maybe separate out other columns that look like other tables, but scroll together as if they were the same table, etc)...  Any input appreciated!  :)

Thanks,
Mike
