I'd go for quality and get the 8-yard Scottish made product from Scotweb.
Though as you are based in the USA you need to allow for the additional cost of carriage and import tariffs if you are buying from Scotland.
I have two five yard kilts from Scotweb which are good value for money and good quality.
I also have a USA Kilts semi-traditional and I can recommend their quality, workmanship and value for money.
