Worth reg. fee. The domain does not appeal to any business type or model. There's no apparent reason why an end-user or domain investor will try to acquire this domain. It is neither a keyword-rich, nor a brandable.
Before a name is registered, you should ask yourself a few questions, including:
Have I identified possible buyers for this name?
Does the name describe a real, popular and profitable business?
Are there variations of the name that the potential buyer can register himself instead of buying mine?
In the case of the last question, have in mind that, in addition to the name not being commercial at all, the plural version is available. So, why would anyone purchase the name from you when they can register the plural version?
Again, there are many factors to consider. I hope these help...
