I've had this problem for a long time. I haven't found a good way to neatly display my controllers and/or keep them readily available. I'm one of those people that frequently plays multiple consoles, and its messy to keep my controllers out. Normally I use velcro ties and plastic bins to store my controllers, but I have long wished for a way to have my controllers on display without having to stoop to hiding them until use. I like collecting weird controllers, some of which I'd never use, but there are many unique 3rd party controllers that I like to have out so people can "feel" them or see how awkward they are.
If anyone has any tips or question, please post!
