i actually just went through this with shaw.... what happens that if the number is not one that shaw "supports" because of firmware you have to dl the firmware your self which is really easy to do through your machine and then call shaw and lie about what model number you have to one that fits for shaw. Once I did that it was painless to get it going because all the last model number means is the firmware. So the key is to lie to shaw about the box you have if it doesn't work and you can get it going. It is a hassel but you save alot of money. I used this guy
pluggy9801 great guy actually called shaw for me to get it setup. ships from texas fedex no brokerage fees and fast shipping. I dont see any listed right now but I would msg him as I think he has a buisness and could probably get you one.
