Need a down expert- side sleeper-

Pillow talk 🪿. I need an amazing pillow. I’ve been browsing through threads talking about down pillows. What high end- not 3,000- but willing do spend money on me that will last? I’m a side sleeper/ back. What do I need to look for in a down? Where to order, I’m seeking mostly Canada and Aus. Has anyone tried the Duxiana micro spring down pillow? That one sounded interesting.
