I have the AR108, it's great for my needs. I don't know how it is in competens with other scanners, it's my first. The best thing is that it's so light, only 95 g without batteries. I like it, have had it since christmas. Thinks it costs around 1200 SEK I think that's about 85 £. I you want a link to the company we bought it from I think I can find it, mail me.
Just like birdwatching - without having to be so damned quiet!
