Add me to the list of happy B-Stock buyers. Got my 990 new, but my 755 was a B-Stock and I couldn't be happier (well, I could be, but that has nothing to do with my Outlaw gear ;-)

I would jump on the 990 if it was still available - maybe you can call the Outlaws and get them to install the firmware update before they ship if they haven't done so already.
