I literally just got this a week ago. I got an Amazon gift card for my birthday and the price isn't THAT outrageous ($16.98 on Marketplace, straight from JP's label), so I figured what the hell. If you're a Petrucci fan or you like Satriani-style instrumental albums, it's probably worth it. On first listen, I was a bit underwhelmed by the songwriting, but it's a guitar album so my expectations were probably misplaced.
Count me among those who can't understand why JP never released it on a real label. It's 2010 and guys like Satriani and Vai are still on majors...you'd think that a guy with the reputation of Petrucci could probably get a deal with somebody decent. Knowing his relationship with Vai, you'd think that a Favored Nations release would be a no-brainer if he couldn't do any better, but as it is, I wonder what percentage of Petrucci fans even knows Suspended Animation exists.
