If you are familiar with Lush and any of their fragrances, FB's dupes are spot on. Citrus Tree is one of their dupes, and it's gorgeous. You can just type "Lush" into the search feature (w/o quotes) and it will pull up most, if not all, of the dupes they have. I don't know your taste in FOs, but I really do like FB. They're one of my top 3 vendors for fragrance.
One of my favorite non-Lush dupes is Bob's Flower Market. It's strong, and it smells just like you've walked into a high end florist. FB's Grapefruit Zest is good too, and it's really strong.
