Shotgunlover,
I can't disagree with the last post. A W&S 700 or any similar decent quality British (and some European) A&D actioned gun gets you about 90% or better of the qualities provided by a "best" boxlock or sidelock SxS for about 10% of the price.
The additional cost to get to the "best" level absolutely is disproportionate but life is short & some people enjoy going through life with nice things that are the best available. If they can pay for them then more power to them. Based on the number of "best" gunmakers that seem to come & go or get absorbed by someone who can subsidize them they probably can't charge enough for what it requires to provide the additional 10% getting to "best" level to stay in business.
Anyway we are straying way OT here.
