I went with AEV and couldn't be happier. Great quality, they are less common than the Mopar Hard Rock/Power Dome, and have a cutout for the snorkel already if you ever want to add it. Haven't had any clearance issues either (put the ARB CKMTA12 under it with no problem).
Another option is the Daystar Hood Cowl. Cost me $400 for the cowl and Line X finish. I thought about a whole new hood but that would have required spending the extra money on the hood, then more money painting it. Then I'd have my stock hood left over and that doesn't fit very well in my garbage can.
So I'm guessing this saved me around $800-$1000. I like it. Might be a good option for you too.
One more DIY option. My reasoning was just like KUCH569's: I didn't want to deal with getting a new hood painted and disposing of my old one. I too went Daystar, only I ultimately chose the dual hood vents. I was planning to spray them Anvil myself, and still may, but when I sat them up on the hood before spraying, with all the other black accents of the Willys, I thought they looked best black. Jury's still out though on whether I should paint them.
If you are doing this primarily for aesthetics, yeah, a new hood will look the meanest. But if you're doing it because you want to let heat out of your engine compartment to protect wiring and other components, these Daystar vents are a great option for 110 clams delivered (Amazon.)
