Does anyone have experience with any of the aftermarket hardtops? I'm having a tough time locating an OEM one around my area. I've looked at Smittybilt, Bulldog, and Hardtop Depot, and they all look pretty much the same. I've considered an OEM one from Collins Brothers, but by the time I get the top, hard upper doors, and shipping, it's about $400-500 more than an aftermarket with hard uppers and shipping. Thanks.
