If you are looking to start a collection you can get a Chimay chalice in the Chimay 3 pack they sell at Costco for around 12 bucks. This glass will be great for Dubbels and Quads. Duvel is also available in three packs with the classic Duvel glass (a must have!) and will be a great go to glass for everything from golden ales to winter warmers. I'd also recommend a decent sized snifter (easily available) for more aromatic brews or beers that taste better as they warm up like Russian Imperials or Barleywines. With those three you should be well on your way to a decent collection! You can also check out thrift stores if you want to save some money. I have found a number of glasses that way and it never hurts to have doubles on hand when sharing a great beer with company.
