The one on eBay is the same one that you have seen in schools ("20J") with a detachable "recording" bell. The differences are that the eBay one is one of the few with an "upright" bell and four valves. semarcus(AT)aol.com also has a very nice four valve one with an "upright" bell for sale. The Marcus one has been used professionally in the Chicago area.
