How long have you had those MBA buildings? Are you happy with them?
I've had them about 3-4 years, and got most of them at once, during a 40% off sale I took advantage of at an online game store. I would say I'm pretty happy with them -- they're sturdy and ready to use out of the box. The "ruin-able" feature in the Middle Eastern series makes the interiors usable, but the casting is a little rough, as you can see, and the interiors are completely unfinished. Overall, I'd give them an average score for quality, but the sale price and ready-to-use factors made them more attractive to me at the time. For quality, I think MBA's Spanish Main series is nicer -- better finish overall, and the red tile roofs come off for access. The cantina and small red-roofed buildings are from that line.
More recently, I've bought some of Old Glory's Spanish stucco line, like the church, and plan to introduce them into the mix as well. There are plenty of locations where Moorish and Spanish/Mediterranean styles are mingled, and they go well together.
