I have the original "Did", the Cobra and I just picked up the Bliss atomizer for Christmas. I can't speak highly enough about them, their awesome (and expensive). With that being said I also have just about every genesis clone that's been made over the last few months including every version of the AGA. The AGA is fantastic! I would also suggest picking up one of the AGA's first. I picked up all of mine in co-ops fairly cheap but even with the vendor mark up your getting a sweet deal, the AGA is worth every penny.
