Hourglass Ambient Light powder dupes?

[CaptainLakie]

I've been insatiably curious about the Hourglass Ambient® Lighting Finishing Powder Dim Light. I want to try it so bad, but I just can't bring myself to spend over $60CAD on a finishing powder. I was wondering if any of you swear by it, or have a dupe for it.

I have what appears to be a discontinued Too Faced product, this "Peach Blur" finishing powder, and I'm wondering if its comparable to the ambient powders, or a potential dupe. 

Furthermore, I'm having a hard time assessing which ambient powder would be ideal for me (should I lose my mind and actually buy the product). I have very fair skin, ivory/neutral. Anyone have recommendations on which shade might suit me best? (For reference I wear TOO FACED - Born This Way Foundation in the shade SWAN). 

I hear that the $30 Hourglass ambient powder is the size of a postage stamp and that really makes me hesitant to drop that much money on so little product. Ahg! It's agonizing! 

Any feedback on these powders is greatly appreciated. Cheers!

@CaptainLakie @I love the Hourglass powders. Honestly I feel the full size one is too much product for me and the mini size is just right. I never hit pan on the full size so I feel like it was a waste so I end up getting either the palette of trios or a mini size.
