Amazon reduced price today on Garmin Nuvi 57LM 5 inch Satellite Navigation with UK, Ireland and Western Europe Free Lifetime Maps. Lowest price according 3camels (averages £96.14).
Note this is higher capacity memory version with Europe lifetime maps. I used this to travel round Spain and it has good build quality and reliable.
Controversy as to whether Tom Tom or Garmin has best UK maps but swings and roundabouts I think.
Stock arriving in 5 days or so.
