£100 is the target (or less) but will stretch if needs be.
Doesnt need to have any frills, just work reliably.
My experiences are
TomTom , good UI but expensive for what it is, customer support reports on web are woefull!
Garmin Nuevi (sp?) widescreen , nice UI but directions not the best.
I have done a web search and the Navman units seem the cheaper end, good ish reports except the fact the maps are well out of date !
So lets hear it , what you got and is it any good?
thanks
John
