Maclean Your dead nut on about price, usefulness and quality, except for file size- that is the 'fourth' criteria. I look at 2 products, one is 15 dollars and another is 20. Both made by reputable ppl. The 15 dollar one has say one temple and is 5 mb, the 20 dollar one has a temple and trees and benches, and is 22mb. Guess which one I buy. File size dosn't say anyting about quality, but it is a guide to quanity. When I see a throne for 9 dollars it seam a little high to me for just the one item. Marforno is a great example of what I'd buy over some of the other building makers, he has more "stuff" in his packs then just one item. So, as the ladies say, size does matter,lol.
