With respect to the official advice you will get from Team-Thorn, it is worth asking the users. The key question is really what you are going to use it for? Are you camping, or hostelling/B&B? Travelling solo or with a group/partner? Planning to ride on good roads, or possibly venturing onto bridleways and rougher roads (I include Coventry city centre under this category!).
Given destination, 26" wheels seems a good starting point so a Thorn or an Orbit would look good. If you're not in a rush, you can also start looking for a good second-hand bike which will get you more bike for your money.
