If you are near an IKEA, they sell cheap as hell glassware of all sizes. The Duvel gift set comes with a really nice glass and a bottle of Duvel
I think the best ways to get cool glassware is buy it as you go places. Look for beer bars that have "keep the glass" nights. Usually these are pretty cool and they let you keep the pint glass (I've got a few snifters this way too). I've acquired a nice collection of glassware this way and it's seems less expensive since you aren't buying them all at once. Plus you end up with all sorts of shapes and sizes.
