One of the earliest lessons I learned about this hobby is that high price has absolutely nothing to do with the way a scent smells. Some $20 scents smell better than $150 scents. Bottom line is if you like it, buy it no matter what the price. As long as it's within your budget.
I think it would be very, very interesting to use a "newbie" as a guinea pig for sampling high end and very cheap frags. Send them 5 small vials of expensive and 5 small vials of cheaper (but still good) frags and get their reaction. No tags on the vials ... just blank.
I wish I would have done that before spending thousands on blind buys or going by others comments.
