You should be able to find an original....I have a used JVC tv which came with a Moteva replacement. It does 95% of the functions for the set. I found original replacements on JVC's website but don't think it is worth the $30!
I use the 1050's remote for the 1050(duh!), my Toshiba VCR, my Pioneer Laserdisc player, my Yamaha 5-disc CD changer and sometimes to power up/down and change channels on the tv.
I use the supplied remote for my Pioneer 563a universal DVD/SACD/DVD-A player.
I was using the 1050 remote last night to operate the tv, and my wife got upset because she had the other remote and felt I "overrided" her!!
