Touring with HP Velo Streetmachine or?

Hi, I'm going to tour around Britain on a recumbent in April.

I was inspired by a couple of books first, Off The Rails about two Aussies journey from Moscow to Beijing & also one written by Josie Dew.

Just had my first ride on a recumbent the other day. The guys at Bikefix London kindly let me have a go on 3 of them. Wow! it was the most fun I've ever had on a bicycle. It was exactly as I expected it to be & as everyone says.

I had previosly researched that I would like an underseat steering model & that the HP Velo Streetmachine GTe was a good touring bike. I knew that it was just theory until I tried one out. Well I got to ride one & it was great.
Anyway has anyone got one of these & can give some recomendation. Or can suggest an alternative & why before I splash out.

Cheers
Nathan
