I actually like this domain because of it's versatility, brandability, and length. Below is a quick overview from my personal perspective on value using Red as negative & Green as Positive.

With the above basic overview in mind I would venture to say that this domain is worth mid $xxx to low $x,xxx in a resellers market and a Mid $x,xxx to low $xx,xxx in an end users Market. An ideal end user motivated to develop and expand an existing corporate structure might even get as high 6 figures.
Please keep in mind that this appraisal is based on my personal opinion. At the end of the day a domain is really only worth what a buyer is willing to pay and or what a seller can convince a buyer the domains worth in their presentation.
