Reading
Guildford
Twickenham (Strawberry Hill more specifically)
Godalming
Putney
Richmond
Surbiton
Kingston
Bournemouth
Out of that lot, if they like Winchester I'd probably look at Guildford or Godalming. THey're on main line stations straight in to Goldalming and have that coutryside/town factor I'm assuming they're looking for. However most of those areas aren't too bad at all really, (althoughadmittedly I've not been in the Richmond/Putney/Twickenham or Kingston areas for a few years now).
