REDFIVE, I know that Marshall Street carries a wide range of Ultralight discs. They are mostly Lightning and Quest, but there are some Innova and Gateway discs there.
Also, Gotta Go Gotta Throw *may* still have a few of the Ultralight Buzzz in stock. They had a tourney stamp on them, but weighed in at about 125g. Last time I checked, they were about seven bucks.
Good luck. And, you might want to post what you find. There are probably others searching for light discs out there, too.
