I would have a longer list than a few (and I don't think mine are SV), except that I keep forgetting to bookmark them, write them down, link them to my email. I usually run across them when I'm looking for traditional prayer or spirituality. For example, if one puts in the search engine bar the name of a solidly trad Saint, one often finds info about that saint on a website with other traditional Catholic resources on it. That's how I usually find them myself: I'm looking for a special traditional devotion, prayer, or saintly bio, and when I find that, I also find a site devoted to tradition in general.
However, usually such sites are only about that, and don't contain Catholic news or discussion. Traditional Catholic sites tend to divide along two lines: spirituality and news+discussion.
Sometimes I find Traditional Catholic theology on a spirituality site, but not always.
Don't know if that helps...
