I don't know about Ronco, but there was a time you could buy anything that ever existed from a tv commercial. They replayed the ads so many times with so many different products that I still remember the number. So if anyone has such a thing you might try 1 800 257 1234. For the record I might remember it, but like most I never dialed it LOL --- On Fri, 10/24/08, lookaround360@xxxxxxxxxxxxxxxxx <lookaround360@xxxxxxxxxxxxxxxxx> wrote: > From: lookaround360@xxxxxxxxxxxxxxxxx <lookaround360@xxxxxxxxxxxxxxxxx> > Subject: Re: more DIY > To: "List for Photo/Imaging Educators - Professionals - Students" <photoforum@xxxxxxxxxxxxxxxxxx> > Date: Friday, October 24, 2008, 7:29 AM > Guys, > > The purpose for the remote is to activate a cable release > with a > gear-motor drive.
