What should I do with Mass Effect 2?

[Munkeh111]

So when Mass Effect 2 came out earlier this year, I beat it twice in about 2 weeks, and got all the achievements, but I haven't touched it since.

So I don't have any of the DLC, but I do want to play it, so should I just get the PS3 version?

I know it will work out more expensive, but are the extra add ons enough to make it worth paying the extra; I would certainly not mind another playthrough (though the first half an insanity playthrough might be a little annoying...)
