I have several orange blossom scents but I find that I I prefer the L'Artisan and rarely wear the others. I don't like either the Malone (too indolic for me) or the Lutens (spicy isn't what I'm looking for in an orange blossom scent.) But if you love those two, then yes, I'd say wear one of them--they certainly cost less than the L'Artisan!
As far as samples of the L'ARtisan go, you can order samples directly from L'Artisan-- at least, in the USA you can. They charge $7 for 5 samples-- it's a good deal:
Luckyscent also has samples of the 2007, for more money: $5 for .7 ml plus shipping:
Should you decide that you can't live without the 2007 L'Artisan, you can still get it for less than the $295 list price. If you order it from Beautycafe.com and use the coupon code "Basenotes" you can get it for 10% off, and the shipping is free for orders over $50.
As far as the 2005 goes, a used bottle of that vintage sold on eBay last week for $300!
