If you buy the Pro Band in a box and realband package here it would be 129 dollars. That includes:
Band in a box 2009, Realband 2009, realtracks set 1, realdrums set1, stylesets 0-3, solist set 1 and melodist set 1.

So all in all, I think if you get realtracks sets 20-27, then that is imo a good deal. If you are missing many features that I just named, then yeah it might not be such a good deal. Still I think it doesnot seem that bad, although I might have bought the megapack for 20 dollars more and have more styles and stuff...

I'll be back...
