Not sure what the price would be for authentic bf Manta, but if it had properly oriented post holes I'd be interested to find out. These two clones are awesome regardless of the silly canted posts.
It is a great atty. The only thing stopping me from buying a second one is the fear that the post holes might be worse than the one I have. It's just my OCD, I guess. It just requires a little more fiddling around with the tails, to get the build the way I want.
