The best place to find info for Extreme Composites planes, in the US,
http://www.bvmprops.com
I bought a 2.6 Edge 540 there before Christmas.... still waiting on the maiden. They do have a LITTLE better site than Extreme Composites, but its not great. If you're interested, give them a call, it saved me a couple hunderd bucks!

http://www.krill-model.com Krill makes a popular katana, a Velux, yak, and other pattern planes... I don't know how competitive these are priced, but they do have a reputation for being great planes.
