Okay, well, the OP has not returned to the thread but here are a few other orange blossom perfumes:
The most realistic orange blossom for me is a discontinued fragrance made by L'Artisan called (no surprise) Fleur d'Oranger. There were 2 harvests, 2005 and 2007 sold in decorated, 100ml numbered/limited edition bottles with a wooden box, and it was re-released in 2011 in a regular 50 ml bottle/cardboard box (probably the leftover juice from the other harvest(s). Occasionally bottles come up on eBay, but expect to pay about $3/ml, which was the original retail price. ($295/100 ml)
Another discontinued orange blossom that pops up now and then on eBay is Victoria's Secret Lace: Orange Flower. This is a bit sweeter than the L'Artisan. No jasmine or spices or powderiness.
Have you tried Pacifica Nerola Orange Blossom? An inexpensive and simple orange blossom. Pacifica now sells sample sizes of the perfume solid. This brand is carried by Whole Foods as well; you may be able to find a tester of it.
Prada makes Infusion de Fleur d'Oranger; the top notes are nice but then it becomes too soapy for me, but that may not bother you.
Jo Malone makes Orange Blossom cologne; I do not like it but a great many people do, so you may wish to sample it.
As you dislike powderiness, you'll want to avoid Fragonard Fleur d'Oranger -- it's very powdery!
