Gary,
There are a number of worthy experimentals available out there. All have their strengths and weaknesses. The Highlander does look very interesting, and from some of the videos floating around they appear to be quite capable in the right pilot's hands.
Are you a member of the EAA? Are you seriously considering building an experimental, or do you want to buy a finished plane?
I decided to self-build an experimental and spent quite a bit of time researching what was out there. I made a couple of trips to Oshkosh, relentlessly called and pestered current and former builders of a number of kit plane models, talked to lots of factory folks, looked at the incident/accident records, looked at the history of the companies marketing the kits, their longevity and apparent soundness and persistence in the market, and especially I flew in anything I got serious about. I also took a long look at the construction manuals and builders support network available for the ones I got really interested/serious about.
If you go through all of the above you will probably find the plane that is right for you, then you really have to decide if you really,really want to build a plane, or just fly it. If you are only interested in building a plane so you can fly that plane, don't do it. Find a finished one and buy it. If you don't really want to build the plane yourself the chances are you will never finish it. Most of the finished kit-built planes sell for little more money than the builders put into them anway, so you won't really be spending much if any more that if you put a thousand hours and a couple of years into building one yourself.
Here is a link to a guy who had a strong motivation to both build and fly his own plane. This link is for the first long trip he took in it, a trip across the US and Canada to Alaska. I've never met him, or even talked to him, but he sure built a nice plane and is using it like we should all use our planes.
