It's on sale quite regularly indeed. And I say go for it whenever you can!!
I've recently started using it in projects instead of EZ and SD and, though I still have to get used to its ergonomics, sonically, it works better for me - the sound isn't nearly as pre-mixed and pre-masterized and scooped, which seems to make it a whole lot easier for me to work with.
The Evil Joe Barresi and the Rock Legend eco-kits from Platinum Samples seem to cover most of my needs for acoustic drums.
EZ is an incredible songwriting tool but I'm hoping to upgrade to BFD 3 whenever I can.
