I think most people are happy with the Facet series that Kerry Sterner designed. You can buy this kit from Greatnorthernmodels in Canada, a guy in my club is building one of these. Also PCM models has the AV8R and DV8R kits. I've been flying the AV8R with a used Simjet 1200 I bought from the RCU marketplace. It flies great and didn't cost too much, it has fixed gear the DV8R is larger and designed for retracts. I know PCM has shipped kits to England/Europe although I'm sure there's more shipping costs involved! A lot of UK flyers like the Boomerang. Not sure if it's available as a kit.
