Sold my Safari top years ago. Too dang noisy at speed. The one @Chris linked is mesh, so you'll still get wet, but they are much, much quieter.
Here's a link to a solid safari style. It requires a header channel to make it work.
I have one of those Alien Sunshades I linked to (had one on my previous TJ and LJ as well), and I have to say, they are a must for any TJ owner. They are quiet on the highway, let just enough sun in to make you feel like the top is off, but not enough to roast you alive and leaved you sunburned.
