Reading thru this I see allot of good advice. On the note of Tandy, I myself have talked to them and was told that once you bought the item (kit, craftaid, ect.) it is yours. There is no trademark on those kind of items. The guy that told me that may have been wrong but he has worked for Tandy for many, many years so I assume he knows what he is talking about there (plus he has given me plenty of good advise on the craft).
