Hi. First time poster here.
I found that the adding the smalljoes.com Apex stands (just the stand parts) to the Ikea Detolf Case($60) is a great way to display your Joes. It's a perfect fit!
I put all my ROC joes on the bottom shelf. In that pic you can see the Pit Trooper vest on the Crimson Neo Viper, it works for me.
Also, while it's not popular, I love the green cammo ROC Grunt from TRU. Actually the whole ROC Senior Ranking Joe set is great even though it is strictly repaints.
