I agree they are really slow, but still kind of a neat talking point. My SSE has it also Cody so if you are checking JYs, don't limit your search to just SSEi.
You'll want to get the accessory bag that has the hose in it to compliment the compressor. Ebay has them now and then and a member had one for sale here not long ago. Check the For Sale section.
Edit: Black94SSEi had it for sale but it is sold. Here is an Ebay link. This guy sells them on Ebay all the time. He must have quite a supply. I think you can buy direct from him also.
