Based on the little I've discovered, Aik, your Zen-On model may be rare. I've found many models and yours is similar to their ZEP 130 model. But haven't seen your model yet, so that may mean it's a good investment as these become more collectable...
...and here's an interesting thread from Harmony Central about Zen-Ons:

).
