Buzz Pro
Very odd goings on: I tried the first link from Ronny and got the site with a pop-up that took some killing; the next try, at Christian´s link, produced the same site but without the pop-up but with the additional info that the Buzz people had gone out of business some years ago!
No idea why my own Google search failed - checked the spelling, too.
Either way, seems I´ve missed the ferry. Thanks for your help, regardless.
