How often do you upgrade your other passions?

Besides an audio habbit, I enjoy cooking and despite doing it less often than my wife(due to the lack of time) I have all home-professional cooking equipment and for "critical" gourmet dinners none in my family can compete. I'm very skeptical in the restaurants and out-dining since there are very few that meet my quality needs and so quite rare I go out for dinner rather than cooking something for my family or for myself something exotic and new. I also taught my wife to cook believe it or not and she keeps my standards. Any guest will certainly notice that we never order pizza or local chinese and all the served party dinner is home-cooked.
Certainly there are other interesting and super-expencive hobbies such as cars, cameras... In this case i'm modest with Lincoln Town Car 1987 and Nikon FM10 25years vintage.
I have to admit that manually operated camera is more fun than an automatic. I also believe that the real car hobbyist constantly upgrades one particular car and do not change it. With modern fuel-injection engines not too much you can do to add the power. Lots of redesigned cars that I've seen cannot handle whatever the engine can through due to lack of knowlege about suspention and brake system that have to match whatever is under the hood or trunk. Suspention of vehicle and body determins the maximum speed more than the engine power.

ooohhh! I almost forgot I love BEER and explore every time extra-ordinary bars that actually produce their own beer or brew on the premises under the trademarks of famous european beer brewers. Getting to the Manhattan with public transportation gives me a possibility to drink a beer with no limitation! Very often I can consume a tremendows amount of beer that can rich three or more liters per one bar visit.
A beer is less expencive habbit than audio or wine i believe:)
