About to jump into getting decants

After kicking around the idea of getting decants, I've decided that I am going to try it. There is one or two Serge Lutens's scents that are from his non-export line that I have been dying to try but didn't know how to get my hands on. That was until I learned of decants from the Perfume Shrine blog and a few other blogs. One of my biggest things is trying to find a reputable site to get decants. I don't want to put my hard earned cash as risk. It doesn't mean that I won't spring for one of the Amouage perfumes that I've been wanting. I'm still no closer to deciding which one that I want. The only one that I have added was Amouage Ubar to the possibility. It always boils down to my paycheck.
