I first really got interested in frags through the knock-off oils. Some of them are pretty good in their own right, even if they don't match the fragrance. Probably the best one I have is a knock off of Silver Mountain Water which is pretty darn close to the real thing. I wish I could say there was a "brand" which I could point you to or an ebay seller, but I don't recall the seller. :/ My fiancee loved her knock-off oil of Shalimar and got a number of compliments on it.
