Just got my very own copy this week (thanks, BGG Santa!)
You must have been so well behaved this year.
I've progressed to metal coins and realistic resources (My first ever bling game ) . I'm keeping the coins in the plastic trays (don't you wish all games had these?) and all the resources in a clear plastic cube with a lid, that the wife gave me. It works great.
The 2 trays were fine though, before the realistic resources.
