I want one of these aircraft. Period.
Why? What is the intended role? VFR? IFR? What experience do you have and level of currency? Where are you going to fly? Who is going to maintain it? How often is it going to be flown? How long are you prepared to building before you fly?
There is a VERY HIGH accident and fatality rate for these category of aircraft. I believe quite often the wrong person is attracted to it for the wrong reasons - sometimes ending in disaster. I would advise people who want to fly these aircraft types because they go fast, or look cool - are inviting serious trouble in the very least. These aircraft are not toys. They are not for the inexperienced. They are not for people who want to go for a "spin". Others have tried it before you and not walked away.
I have built and flown 2 lancair 360 aircraft and I have enjoyed many hundreds of hours in them. However - the enjoyable flying charateristics can be the undoing for some people- ie light control forces, marginal longitudinal stability, rapid roll rates, high wing loading, high approach speeds and stall speeds, light weight/low inertia aircraft.
I find them very enjoyable to fly - but when they bite - it can be without much warning and the consequences can be severe. A very healthy respect for the aircraft characteristics, serious discipline, complete situation awareness and an over riding desire to stay out of trouble and alive are required.
The building process was overall very enjoyable and rewarding. There are many knowledgeable and interesting people that you may come across through various builders groups throughout the world and the SAAA. The knowledge that you gain and the friendships you make is fantastic. But be prepared to be building for many years. The building is really a fundamental part of this aircraft category.
oldm8 - I most respectfully suspect by the tone of your post that this may not be a suitable aircraft for your purposes. Do not be disheartened - I am sure that there is another aircraft type out there that would be more suitable and sustainable for yourself - just keep looking.
Good luck
