The Amazon prices look rather extortionate. The price at the IRIS site is around $140-$160 (US) that the first converter I found says would be about £90. Of course there's that shipping and VAT ...

I'm aware of the scanner only because I use a pdf converter with links to the same tribes, and get (annoyingly) frequent advertisements. The scanner has been offered here for as low as about $90 (US) in the ads, but of course that's local delivery. A search for "handheld image scanners" or something similar should find other options. (If you just search "hand scanners" you'll get mostly barcode readers.) The most similar "bar/stick type" ones with the decent reputations tend to be significantly more expensive rather than less, from what I've seen without doing serious research; but you might find a deal if you poke around some.

There are cheaper devices of vaguely similar kind, but ones that don't do a good job often are less satisfying than a lazy hooker one might hope for.
