If you think Zeta are good, then you`re in for a pleasant surprise when you try some of the other instruments that are available, but less known.
I play a "Bridge" electric
http://www.electricviolins.com
It is a hollow bodied kevlar and carbon fibre instrument, and has a fine acoustic sound (for an electric), but is instantly playable and setup. I also have a Zeta Jazz 5 string. In comparison, the Zeta has a very thin and metallic sound, while the Bridge is full, and quite warm. It also looks a lot better.
All I`m saying is, shop around.
