Been reading that the older AVRs are really good for sound, and can be had for not too much. So kinda got focused on older Yamaha RX-Vxxxx series avrs. What I have been noticing is that , in many cases, especially on ebay, there is no remote included. Have found that often, the remotes sell for about as much as the avrs. If I were to buy a Yamaha avr without a remote, would I be able to use most of the features, just work it manually, or is a remote kinda necessary, even for basic stuff? Also, does the remote need to be a Yamaha remote, or can just about any remote be programmed for the avr? Appreciate any input, opinions.
