FT,
Ah, SmartHawke beat me to it: I was going to suggest the Vans series. I'd also include the RV9 in the list, there's now a couple of these flying in the UK. If you want info about Vans aircraft in the UK the best place to look is
The UK RV flyers' website
I intend to use it for business travel
You need to be aware that in the UK (and the rest of Europe I suspect) kit built aircraft are restricted to Day VFR, and are not permitted to fly over congested areas
