I believe that a used RBL would do well for you. I have one that I've used heavily since the first year the Launch edition was introduced. I had to wait 9 months for it, but then I only paid $2500 for it at the time. I have never had any issues with it. My gun has a French Gray frame and double triggers that Galazan reversed to left hand use. And I had the stock bent to left hand cast on shortly after receiving it. I have ordered a true left hand gun to replace it, but were it not for the right hand opening top lever on the RBL, ordering the bespoke gun would not have been necessary. From what I see in the market, you could get a used RBL for around $3K and a new one for about $5K, depending on what you options are ordered. I would suggest a self opener if you order new.
