Hi and welcome...
I'm sure you will find a few members around Salisbury.
With regard to new bikes, try Mikkie (he runs the used bike section) at Blade Swindon. http://dealerservices.autotrader.co.uk/273841/index.htm

A fair few members have bikes from there.

Hope to catch you at Wincanton sometime or the club day at the Harp & Crown on the 24th.
Cheers
G
