Spread across all grade levels, I use many different resources. I tend to look for programs based on subject rather than aiming for an all-in-one approach. So, for example, our reading/writing/spelling programs are from companies that specialize in language arts rather than being specifically Traditional Catholic.
However, I do use one Catholic company for quite a few things and that's Homeschool Connections. They're not exclusively Traditional, but they're conservative enough that we use many of their classes, including religion courses. (I've only come across one that was a little too N.O. for us.) Unlimited access to as many recorded classes as you please costs us only $330/year. We've also done some of their live courses.
A few courses we're currently doing: HS Chemistry, MS Geography, MS History (based on a Catholic textbook), Advanced Spanish, MS Applied Science, AP Computer Science, MS Baltimore Catechism, and a literature class based on Little House on the Prairie.
Some other companies that I currently use or have used and liked:
IEW.com (owner is Catholic, so you won't find anything offensive here)
AllAboutLearning.com
MathMammoth.com
MemoriaPress.com (they cover all subjects, but I mostly use them for Latin and handwriting resources)
PamelaWhiteWriting.com (live classes)
KhanAcademy.org (many subjects, but I wouldn't use this for anything other than math ... I only list this one because it saved my sanity as I could never keep up with math lessons before switching to Khan Academy)
