but I wasn't very impressed with the re-routing when I deliberately went off course.
Sorry but I have to disagree with you, or at least with my "original" TomTom One.
Like yourself when I first got it I tried all manner of wrong turns and only once did it want to get me back on the same route as from where I deviated from, it may just be the area that you were/are in at that particular time.
Not to mention the ease of planning a journey with the full 7 digit postcode, although I believe more and more Satnav systems have now followed Tom Toms' (who were the first to use the full postcode) system.
And did I mention the Speed cameras, don't buy them from TomTom,
www.Pocketgpsworld.com is far cheaper and superior at only £11:00 per year or £2:00 per month if you want, which also give you access to "all of the different brands of satnav systems" so if you have two different ones, you only need pay once (but thats probably cheating).
I did try the Medion to start with (borrowed it from my neighbour) but did not like having to fiddle with the different buttons or the tiny stylus that came with it, it was very confusing,
give me the TomTom every-time.

But not for the Medion (I just looked for my friends Medion SatNav)
