Has anyone tried the expansions for Borderlands? I believe that there are now 2 (i think they maybe adding another one soon that supposedly increases the lvl cap) @ $9.99 each. Are they worth it? Do they add a lot more content and fun or are they just money grabs? Would you recommend them? Do you need to added them in order or can you pick one or the other? Once my new credit card comes i'm very much thinking of getting these expansions.
