Being in the sign business, nice neon work. And anyone who wants one for their own use. Take a good picture, call a local electrical sign company. Ask if they still have a neon plant, and if not they will know who in your area does. Then take the picture, and the size you want the piece to be, to the local sign company and they can give you a quote to build it. The smaller company's, that still have a neon plant, will be more affordable than the larger companies that focus on big signs. Same for repairs, find a smaller local sign company with a neon plant.
Oh, and regarding copyright, if you just have one made for your own use, unlikely anyone will chase you for copyright infringement.
