Well for some reason ch web page and cataloge order info comes up with A&J hobbies logo on top of the page. If it is just a link why would it be apart of a&J site and not a direct link to ch instead. Could it be that A&J may be hosting there web site. It would seem that if you are in business it would make sense to sell there items to make profit rather than advertise for them. But I could be wrong not affiliation at all.
