Update:
Thanks for all the input guys. I ended up getting my hands on a new Rizzin Br550 in a 16/20 combination. Maybe not entirely practical but having a 16 is something I've always been interested in. Was able to take it out over the weekend for the pheasant opener and really liked how it felt and performed. Not as dainty in feel as some of the Spanish guns that I've been able to get my hands on, but being able to check it out in person and having the dealer in state gave me some much needed peace of mind.
