3 word names are very difficult to sell, if at all. With this one, I think very niche people may want to develop such a name and even if they do, what's stopping them for going for brandables. Hence, to me, this is a reg fee name.
Adwords keyword planner says range is 1-10k, keywordspy says 5k for the singular term (around 5,500 searches per month) but nothing for plural. While there may be organic searches, its extremely niche, and will be extremely hard to sell. Little value / not worth reg fee. Id let it drop.
