Quoted from Kwaheltrut:I've never done a full playfield swap. If I did, it would have to be a game that I was keeping. The amount of work that goes into that just isn't worth the return you might see selling it.
Depends on the game, I’ve done swaps on several games and the increased value has allowed me to trade “up” over the years. I hold onto my games longer than most people I know and I only sell or trade a game if there is something I really want to replace it, just did that with a GB for an AIQ.
