Hi, I'm not a big stock player but I do dabble.  I think you made a good buy @ 2.83 on your Sirius.  I will be buying more.  It really depends on you outlook on your investments.  Are you looking to play on a daily basis or a long term investment?  Sirius is a tough stock to play on a daily basis but you can make money because its usually a pretty active stock.  For the long term it will probably jump to around 4 to 4.50 a share once the merger officially goes thru.  Since Sirius is buying XM it (Sirius) is going to have to prove themselves, which they will, and eventually, could be 2 to 3 years, where there stock should be a solid stock trading in the teens.  Of course that would be long term for Sirius, now for XM, when the merger goes thru I believe that the value of thier stock will drop a possible 4 - 5 do to being bought out  by a company of lesser value.  That would be a good time to buy XM (when it comes down) because it will bounce back quicker because of its overall value.  Exactly why Sirius wants to merge.   Good Luck.  And honestly if you can get and hold onto stock under 2.89 I believe you can't go wrong in the long run.  Even tho its volatile its going to jump when the merger finally goes thru.
