Just thought I'd mention that I was finally able to see Sirius B through my 155mm EDT at the Winter Star Party last week. I first saw it in an 8" TEC apo, in which it was quite easy at around 500x. Knowing what to look for, I was then able to see it fairly consistently in my 155 at powers above 400X, a delicate point of light farther from the primary than I had expected. It was also visible through Sue French's 10" f/6 Dob.
