Digital Signatures

Anyone have any suggestion on where I could get a cheap, if not free, digital certificate whith which I can then sign my installer packages? Some folks probably aren't real crazy about that "can't verify creator" (or whatever it actually says) message that pops up when they start to run my installer. BTW, I'm using INNO to create the installation package, if that matters.

I know its probaly not cheap but I dont think you will find mush in the way of price variations, but Verisign is the primary source
for Digital Signatures. ;)
