Really nice collection you have there, it would look really nice if you got some nice shelves to display them (the ones I'm using are from Ikea, and they're relatively inexpensive)...
I completely forgot about that splinter cell case, any chance you could post up some details about it you might now (the official name, where they were originally sold, and how much they originally sold for, etc.) it's not in the database, either and that's one release I wouldn't mind adding to my personal collection.
You might be interested to know that I live up in NH, Tilton to be exact. I know you said you never get a day off but if you ever find yourself up in the lakes region you're welcome to stop by, just shoot me a message.
