I've had a RM-VL900 for a few years now and love it. It accomodates my entire home theater system; Receiver, TV, Digital Cable Box, DVD, VCR, CD, Cassette Deck (MD-A Deck and TAPE-B Deck).

After reading the manual for the RM-VL600, it appears that this is a replacement for the 900 not the 710. Am I wrong? My 900 is showing signs of physical ware but functions perfectly. I am trying to decide if I should replace it with the 600 or buy another 900. The 900 is listed with some online merchants, who appear to be questionable with customer satisfaction. The 600 is readily available. I would appreciate any advice.
