I am actually ranking for a very similiar keyword. Your market samurai seems analysis pretty much like the one that I have for mine

, so I may say a lill bit about it.
I started with a MNS in this niche 3 months ago. Since then I have built 2000 backlinks according to webmaster tools and have established pr 3. This has taken me now at position #10 for this keyword. I am not very skilled in SEO, yet but I begin to get a feeling for it.
I would definately go for it if it's a high traffic keyword or something with a good CTR. Seems like you want to learn SEO like me and doing so at a keyword with NO competition at all shows nothing.. I mean you could build 200 bookmarks to your page and if your competitior has 40 backlinks in total you will be 1#. You learn just nothing from that.
Your competition has authority, bad onpage SEO, search-engine-unfriendly-urls and very little backlinks. The #10 one seems to have absolutely garbage links at his ranking page, else he would have been ranked much higher. Further more you could have a kickstart if you manage to get a link at the yahoo answers page at #6.
best wishes,

PS.: Don't post show urls in your screenshots if you have found a niche that you really want to monetize later. If you show the urls, it's pretty easy to know which keyword you are trying to rank for. Oh and I have spoken about this one :_)
