Sorry to hear that you had trouble with an HP product, we've got about 2000 of them worldwide and very very few problems. The K80 I have did need me to download the latest set of drivers as the support disk it came with was for HK and spoke Chinese at me - it was also outdated against the latest drivers, as it had been cut in Mexico some 3 to 6 months previously .... but that was just a download, so I don't really count that as a major SNAFU.
Good luck in your quest. Gofer
