god, there are times when i wish i had only 35 figs to make space for...
in your case, i would consider either adding some additional shelves to make the needed space (there are a ton of plastic shelving units that are sturdy and still w/ rounded edges and such so the kids don't bean themselves retrieving figs... we're well past that age in my house, and we just moved to some industrial steel and wood plank shelves that house the kid's tv, video games, and boatloads of toys, and then we have large plastic bins stacked in the closet... like seven bins. and there's a large one in the garage, like hoffa sized... and of course, there are bins outside the closet that won't fit in there, but are nonetheless toys so they go in the toy room... it's scary when i do the math, or remember the back pain elicited in bringing them all into the house.
just saying man, i acknowledge that my (and by extension, my kids) collection is really just shy of being a horde. not like, the Evil Horde, but like an evil horde... so please, don't take my advice on figure storage. i have huge plastic bins, stacked full of stuff, i have like two bins just devoted to accessories and dios pieces that aren't directly related to the larger playset pieces i have out on display... i have WAY too much to be considered rational anymore.
just saying... if it were me, and i had it to do over again... if i couldn't get it one two or three shelves MAX, i would stop buying. it's togh, when you're as far into a collection as i am, to give advice to a newer hobbiest, cuz every idea i have would accommodate like 100 to 200 figs, and i would still be planning in my mind what to do w/ the rest of the bins... trust me, keep it on shelves, maybe two, maybe three, no more than 75 figures. i will say this, we had one of these units http://www.samsclub.com/sams/shop/produ ... tId=142481
in our old house, and currently in our garage. it's very sturdy, rounded edges, and holds a cubic buttload. if your collection ever exceeds it's capacity, you have too much.
that's as close as i come to practical advice.
sorry this is so wordy. just saying man, know when to say when. there's a point where the little plastic bastards have ganged up on you, and you look around and realize it's become a lifestyle.
