Just ordered one of these, from HP's own store. It is twice the price at Tesco, and over £190 at most other online sellers.
Seems a fantastic price for: print / scan / copy / fax, built-in (not optional) duplex, wireless, borderless. Scans and faxes over a network, and reports say the photo quality is phenomenal.
Reviews at Reevoo are great, though I found worse ones elsewhere. However all of the bad ones related to bloated software and difficult setup, and it was suggested that both of these are solvable by (a) downloading latest software rather than using the disk supplied, and (b) doing a custom install.
