The point was can you get your money back if you have to sell it? I have seen things where a guy bought a gun for a large amount of money and later could not recoup his money when selling. Case in point, commemorative guns currently advertised in magazine. The set on tables for sale at figures lower than what the original buyer paid.
Some will say don't bother about price, if you pay too much it will be okay if you keep it long enough for the prices to rise. This attitude does not account for inflation and present value theory of money.
