Raleigh are now little more than a name badge, so do not think that this has much to do with the Raleigh you knew. The first question to ask is what other riding you will want to do afterwards: loaded touring with camping gear, long distance tarmac riding at a somewhat elevated speed (i.e. audax), semi off road, or commuting?
In my view Thorn have the nicest range of touring bikes in the UK, but there are a few alternatives. Have a look at their site (
www.sjscycles.com) to see what types of bike one can choose from, and for what types of riding. These bikes have good price performance ratios if you refrain from too many upgrades, and they have no hidden weak spots like shitty wheels and tyres, crappy el cheapo bottom brackets or headsets, brakes that are more cosmetic than real etc.
A decent second hand Dawes Galaxy with drops could be a budget alternative.
Enjoy the ride,
