Hi! Since you've tried MAC, I highly recommend Victoria's Secret's Very Sexy Loose Powder. They have it in three lovely shades (a gold, a rosey/pinky broze, and a gold bronze), and it highlights very well. I use it on top of my blushers all of the time, and it looks gorgeous! You can also use it anywhere else on your body, not just your face! I own this product in the colors "Show and Tell" and "Role Play".
They are originally $18 in stores, but they were on sale online for $6! And it comes with a lot of product! Check it out!
