G'day guy's!

I'm in the market for double .500. I'm thinking about a Merkel 140 or a Verney-Carron Azur Safari but I'm confused about what would be the better gun (i.e. stronger, better built and regulated). I'd also consider a Kreighoff but as I understand they don't make an ejector gun??! I want an ejector.

I've heard some bad things about the Merkel 140, but this criticism was issued by someone who sells guns by another big German gun maker....Namely that they shot loose very quickley, particularly with the big calibres i.e. .500 and .470.

Can anyone give me some advice.
