Agree 100% with the sentiment, buy the gun not the name. There are some great non british guns out there that do not demand the same price for close to or in some cases better quality.
Many of these guns will serve any user well for a lifetime of use.
However one thing must be understood, investment grade guns that appreciate better than others are high grade British and American guns.
While I take great pleasure in the quality of an off brand high grade Belgian gun the reality is any resale is a challenge. That is a problem for my heirs (damm them if they don't hunt with them as I have)
That said I buy guns to use not resell and would recommend a quality Spanish gun to anyone who like me wants to shoot the thing and not stare at it on the wall.
