What Experimental(s) Would You Pick?

Lately I’ve been thinking about if I were to ever build an experimental aircraft what it’d be… I’ve thought of three aircraft of varying prices.

1st would be the Wittman Tailwind.

2nd would be a Team Rocket F-1.

3rd would be something like the Lancair Evolution.

As you can see, the price ranges from reasonable to insane.

What would your pick(s) be if you were to build an experimental? Try to pick at least one that is rather cheap to build. Looking forward to seeing everyone’s picks!
