I would wait a few months before starting playing, playing a MMO at launch is almost ALWAYS a mistake and it's gonna be even more so in SWTOR case because 1st tons of peopl,e are gonna want to play at the same time and you'll have to deal with login queues and servers crash and 2nd because it's Bioware's first MMO so it's pretty much assured it will still be bugged quite a bit at launch (it still has a few bad bugs and it's only a few days away from the head start).
After a few months the most glaring bugs will probably be fixed and you'll have a vast pool of reviews and opinion to base your choice of getting the game or not on.
