what's a good country for a homebuilt aircraft?

I currently live in the Netherlands and I'm looking to relocate.
I've long wanted to learn to fly and build a light (experimental and/or
ultralight) airplane and I'm wondering which countries would be well suited
for that, economically and with regards to permits/licenses.

The US seems to be in the lead, but the Australian regulations just
loosened up a whole lot. Don't know about the relative cost of living,
taxes, and all that, or where the kits, fuel, etc, are cheaper. US
insurance and liability are out of control, though. Maybe somebody else knows.
