When you search for blank tape on ebay, use the key word "NOS" after "reel to reel tape." This will search for tapes in sealed boxes and "one pass," or lightly used tape.
Mind you, the selection ranges from older poor quality tape to high quality mastering tape. You should familiarize yourself with the different tape stock if going into this hobby.
