We've got a great bar/grill around hear that sells their beer of the month in collectible glasses. That's where I get all my glassware. For 5 or 6 bucks I get beer and a logoed glass to go along with it.
This month is Hoegaarden, and they have the GIANT hexagonal glasses. These things weigh over 2lbs, are 7" high and 6" wide at the top. I believe that they are 32oz. Filled with hoegaarden on tap, I was able to pick up two for <$15 (I made SWMBO order one, and drank it myself - at least as much as I could). I found a single empty glass for sale online for between $15 and $25.
I just wish I hadn't missed Pawel Kwak which comes in some neat glasses.
I do need to order myself some Guiness glasses one of these days though, thanks for the links.
