Here are some links to TBC merchandise that I am aware of:

• DVD - Yes, TBC is available on DVD!. I have a copy myself and must say that I am impressed, although I have read some bad reports about it on Amazon. I must say though this is my first time watching a DVD, so I guess I was easily impressed!, in either case it's FAR superior to video!. The sound is mono, but who cares. There are production notes on the disk as well which give a good insight into how the movie was made.
• VHS - The video is readily available in NTSC and PAL versions.
• Sountrack CD - I finally got a copy and it is fantastic, nuff said.
