I dabbled in getting my photography cert via SAIT till the realities of life caught up to me. What I found was that at basic to intermediate levels, good photography is good photography and that tips on composition are equably applicable across digital and film formats. I wouldn't worry about "digital specific" courses if your intent is to take separate Photoshop courses.

As with any course, how good it is will be dependent on the instructor and your learning style. I had
George Webber who takes some incredible portraits - didn't focus on the technical details (he left those for the course handouts) but was more hands on in relaying his experiences as a photographer.
SAIT is nice in that they have a selection of courses for you to choose from. You can pick and choose from them - even if you're not pursuing a photo certificate. I did the Intro Photoshop course and found it quite useful - I was hoping for more RAW work but I think that's in an advanced course. I also took the night photography course but didn't find that to be all that enlightening (ooooh bad pun).
In all I found them really good - I'd recommend on taking anything outdoor related in warmer weather as I rapidly learned that outdoor photo shoots really suck in -20 weather.
Though the certificate has the best course name I've run into: How to make money with your camera
