I would have been a heck of a lot better off if a few years ago I had spent all my money buying Rolleis instead of putting some in the stock market. My Rolleis are worth more and my stocks are worth less.
That said I don't know how much more up the Rollei prices can go. Surely they are topped out.
I don't think the original poster really meant an investment minded investment. I think about the money I am investing when I fill my car with gas... nice little investment.
