I've seen a few threads about people looking for Supertone Horns. I was in my local Circuit City and they are starting to carry perfomance parts for compact cars. In the Car Audio section they have a catalog with lots of accessories including Hella Supertones for $70.99

 

get in touch with bsetiawan (an org member)...he might still have some for sale, and as I recall they were way less than $70......that said, good info to know that they can be gotten thru C/C

 

i may be selling mine......pm me if interested..
