The reason I asked if you have an IKEA close by is that shipping is pretty much out of the question (it's something like $250 to get a $60 detolf shipped ).
There are other curio cabinets on the market, but detolfs are very popular because they are the perfect size for 1/6 scale figures and they are quite affordable. You could try checking eBay or Craigslist for one. Otherwise just search for "curio cabinet" at different store websites.
Great Bats collection!
It actually hurts to not have any Bats or Joker in my collection
I have Year One, Killing Joke, Long Halloween, and a few other trades that I love. I really wanted a DX01 & DX02 but I refuse to shell out that kind of coin to have a crappy PERS Joker & leaky abs Batman. Maybe some day though!
