FF - I think the extra Db was roughly $100, probably about 12 mths ago.
Stuart - I can email pics at weekend if you PM me with your email address and I can find my digital camera! However, its about the size of an A5 book (Maybe a little bit bigger!). The screen is very clear and you can even read it in turbulence which is a bit of a problem with the smaller screens.
IO540 - The US also does the European database as I ordered it all in one package from them. They are on a card and the unit I have has two card slots in the top, very easy to swap over.
If you PM me I have just checked my phone and have to phone number of Avmap I used when I ordered it, not sure what the guys name was though!
YOu are right that it is poorly supported and a lot of people look at you blanked faced when you tell them what you are using. The other -ve I forgot is that the flight planning software you get with it is absolute pants!
