I haven't seen it mentioned in this thread, and this is very important, that Sasktel can only provide HD to one set top box in your house.
Therefore, you can now have Max on up to 4 TVs, but only one of them can be HD.
That, along with the absence of an HD PVR for the foreseeable future are potential deal breakers in my opinion. But thats just my opinion.
So, getting back to Jeff's original question I would offer this:
If a PVR hasn't been important to you yet, and you have no need or desire for HD on more than one TV in your house, then Sasktel might be the option for you.
Finally, if high speed internet is important to you, you might want to check out Shaw vs. SaskTel comparisons in that department. But thats for another thread.
