I've got a Europa. I didn't build it myself, but bought it with 20 hours TT. I then converted it to a tri gear (I really don't like the mono's). Total cost around £35k. It now has an EFIS and Autopilot also.
Great fun to fly, 120kts, <15 litres per hour mogas, trailerable, just not certified for aerobatics in this country (it is in the US but I guess that doesn't help much?)
