My collection currently takes up 4 curio cabinets and 1 shot glass case. I'm fixing to downsize though. Are you collecting both 9" & 3"s? If you're just collecting the 3", Michaels has the shot glass cases that are the perfect size and will hold quite a few. They also have them on sale frequently. I don't know if they still do, but the Container Store carried display cases that were perfect for vinyls. It's a closed in display with tiered levels and if you set the tiers like steps it will perfectly hold a series of 12 vinyls. For 9" figures you'll most likely need a curio cabinet. Ikea has some really nice ones and those go on sale on occasion as well.
