You will likely want to check out the remote for whichever model you get. Not all of them have the ability to switch layers without the need to be in an OSD menu. The earlier Oppos, Sonys and Denons had this, but the more recent versions do not. That means to select between Multi or Stereo layers, you'd need a display if the model you choose doesn't have this capability on the remote.
IMO, a used Oppo 105 would be what I'd look at. The 205 tends to be too pricey since it supports 4K, but the 105 is 1080p only, so you can find them for less. I have both and the 105's DACs are very close in sound quality to the 205 for SACD/DVD-A.
