My advice on it is wait... Wait for Big Lots to get in their Christmas stuff (usually between August and October), or wait to see what Penney's stocks/gets in. They had the Command Center in over the holidays IIRC.http://www.jcpenney.com/jcp/X6.aspx?GrpTyp=PRD&ItemID=16e86d3&DeptID=52440&CatID=77791&SO=0&PCatID=52440&CatSel=4294939233%7cview+all&NOffset=0&Ne=4294957900+4+5+1063+1008+8+18+904+949&CatTyp=RLE&Dep=Toys&N=4294939233&Pcat=Toys&Cat=Boys&Nao=0&PSO=0&CmCatId=52440
They've still got a number of other sets, and Penney's has coupons all the time.
That bridge? It's the primo piece from PTE if you ask me. And in that set you get the tower, the bridge, the "steel hedgehog" obstacles... That set's friggin' great.
While I like the "Pizza Hut" Command Center, I would have to humbly disagree on it being better than the 3-story building. Only because the 3-story building is more a realistic looking design... It fits in with Tatooine for instance, or North Africa in WW2, or Italy in WW2, or basically anywhere we're blowing up right now like Afghanistan, Iraq... It just fits in to so much, honestly.
The Pizza Hut rocks though, but it's a more modern looking building, and is smaller. I got 3 of them in what I hoped would be an attempt to put them all together to form one big "complex".
What I really miss is this modular set from Eversparkle. It was glorious. I got two of them, and a few extras from a friend, and I feel fortunate to have those. They make these really bitching little buildings, stackable or expandable in ANY direction. Walls are just thin plastic sheets, but sturdy enough and featuring some detailing. I go tthem years and years ago, they're long gone from the net now it seems. And they were the inspiration for modular Star Wars sets in my mind... I got these back when the FFURG Email Listserver still existed even, they're that old. Cheap as hell figures, cheap as hell accessories, but the set was everything.
PTE continues to impress though. They're cheap, they're almost always abundant around Christmas, and PTE continues to put out new stuff... Every year they do something different (well, not EVERY year, but every other year they've pretty steadily delivered something new).
Towers though? I've got dozens and plan to use them all. And that bridge is something to behold with a platoon of Japanese soldiers rushing across it, or some German infantry, battered and bruised, trying to limp back across the Rhine, or some cold-weather U.S. GI's making their counter-attack after the Bulge failed... Lots of cool scenes that bridge is great.
