I think the swizzles make a great collection. They are inexpensive - I think the most I've paid for one is $3 - and they are available. You can find them in antique stores and flea markets. The variety is amazing - the older ones are quite imaginative. Probably one of the hardest sets to get is all the colors for the old Flamingo - I think everyone must like flamingos. My wife sells them in her space at the antique store for $1 each.
