check the interiors section there are loads of threads, my personal pick is garmin (nuvi200 for about £100- i have a 610t £200+, but its amazing with blue tooth calling built in and free lifetime traffic updates), and a subscription to pocketgpsworld.com, for their excellecnt speed camera data base (£19 a year for unlimited down loads so if yu have multiple units you can save on more expensive subscriptions to the likes of tom tom and garmins own)
