Thank you! Good informationI believe that everything you see online is pretty much coming from the same source, so it doesn't really matter who you get it from. Personally I buy things like this from PG Classic or Classic Inds depending on pricing (which is normally very close).
One thing I will say after just recently ordering an entire AC system from PG is that they do not say whether it is in stock or not so if you order from them and it doesn't ship quickly it means they don't have it and it might be awhile.
