I think you are right about the upgrade path Meridian choose to not go with on the G series. That makes the second hand prices hit rock bottom!

Provide an upgrade path and the long lasting value will prevail imho. From the enthusiasts.

This is exactly how I feel about any component now wether Meridian or Lexicon etc. Either be cheap and non-upgradeable. or be expensive and upgradeable. The problem is, the G series isn't cheap. Therefore you hit rock bottom on used gear prices.

The 800 series is too expensive for me new so it's not on the map here.
