No, if you consider collecting wedding hats a hobby.
I used to be into high end audio equipment. Nothing is expensive compared to that. 400 dollar vacuum tubes, 1000 dollar speaker wire, and all the other nuttery that comes with it. Just go to Audiogon.com and check out the prices for used gear.

Remember my post a couple weeks ago on the $1000 Popsicle? I have friends into really tricked out guns that cost thousands. My neighbor restores antique cars that are worth the price of small houses. We're all crazy :-)
Wine. Whereas most collectors have a few dozen or may a couple hundred of whatever it is they fancy, winos often have several thousand bottles in their cellars. I know one guy in Napa whose cellar has been featured in Wine Spectator a couple of times -- over 5,000 bottles, many large format (i.e., Magnums, Jeborams, Methusulas, etc., some engraved), easily worth a couple million. Top-end wines from California can run a couple hundred per bottle, and the best Bordeaux can be over $1000 per bottle when new. Add a few years of age and the prices can easily double. And unlike other collectibles, wine gets consumed.

As hobbies go, collecting kitchen knives is not all that expensive. Of course everything is relative. If you're making $25k a year then you might think collecting pricey Japanese knives is very expensive but compared to collecting cars it's really cheap. How much more fun is it to collect cars than kitchen knives? Depends on who you are. I'd rather collect kitchen knives. I've had a lot of fun learning how to sharpen and collecting knives worth the effort.
It is better to remain silent and be thought a fool than to open your mouth and remove all doubt.
Well, my wife likes to say when I get caught up in knife geek stuff: "At least you're not out whoring." I think that is pretty funny, but she is probably right. Frequenting prostitutes would be pretty expensive I bet and there is nothing to show for it.
