I've had my F20 NAVMAN for about 18mths and it's not put a foot wrong. It cost me £150 18mths ago. Always gets me where I need to go, even if it's not always the way I would have chosen (but then again... if you know where you are going, why would you be using your Sat-Nav?). Very simple to use, my wife uses it more than me as she has to get to various clients houses in central belt..... and she has no complaints.
We've used it for various jaunts, from Aberdeen, Loch Fynne, Blackpool, I took it for getting me from Gatwick to my hotel in Guildford..... it's never got us lost.
It's cracking wee unit that is compact and has all the functions you need without all the nonsense you don't... 2 buttons are easily located to get you to nearest parking or nearest petrol station. 1 button to get you in to the menu, 1 button to get you back to maps.... all the rest is touch screen.
Comes with UK Maps loaded, Point-of-Interest (ie, camera's) and you can purchase a seperate T1 plug-in unit for about £40 if you want free traffic updates for life with no subscription. I personally never bothered with that because the T1 unit needs a seperate power feed from what I could make out (I might be wrong with that assumption though).
I think the S30 unit is the new one from Navman which has basically taken over from the F20. That retails for about £100.

I've been watching a few of these on eBay and they are going from £50 up to £65 2nd hand.... I have all the 'bits' and I'm sure the box is in a cupboard in my office. It's in great condition still and all I'm asking is £50 ovno. If no-one want's it then I'll probably shove it on eBay but thought I'd post on here in case anyone is looking as it would possibly save postage & hassle etc. Probably leave eBay until after the weekend, so PM me or email gorrieman at hotmail dot com.
Oh... just so you know.... only reason it's for sale is that I just purchased a new NAVMAN S80 today. Bigger screen, but so far I am actually preferring the F20... doh !!
Apparantly there are some S80 updates I need to make my new one work better...
