Dude, yes jet "tidbits" do cost alot. I remember that when I had a fleet of jets, I was spending almost $1000 USD a month keeping them up, buying this or that.
The UAT is a perfect example. I have tried some other VERY reputable brands and have even liked them. But like dating when you're single, they are necessary evils in my book. And like dating, they are about $100 a pop!

Expensive for sure.
