We seem to be in the very same boat here! I too am looking for a RC-855 Remote. I bought a AVR 1700 Reviever from Best Buy in San Diego about 5 or 6 Years ago. It was sold as a demo, and there was no remote. I only reciently have been looking for a RC-855. I guess I should have bought on back then when they were a heck of allot cheaper. If you find anything out, please let me know. I'll do the same. I found a few sites, but the prices were outragious!
Talk soon. Greg (hafengr)
