Each has its own strengths and weaknesses. Hopefully you'll be able to pick one that fits your needs. I lived with each of these cases over the course of at least a week to get a good feel for what they were like in daily use. All the cases had belt clips, and I wore them as a regular part of my wardrobe.

Rhodiana Visor Case
The Rodiana case at http://www.rhodiana.com/products/palm/palm.html is one of the more interesting cases I've seen. The case is made of ballistic nylon and is well padded all around. It's pictured in Figure A.

The cover has an inside pocket that holds an optional piece of Lexan that adds some stiffness to it and hence some more protection for the Visor. I strongly suggest that you get the Lexan stiffener. It's well worth the $2.00 it costs.

When you slide the Visor into the case, you'll have to snap a clear plastic cover over the top. This makes using any but the smallest Springboards impossible. The plastic cover acts as part of the lid's hinge as well as the entry port for the Visor. It also helps keep the Visor in place when hanging from the belt clip, since, like in the Covertec case, the Rhodiana hangs the Visor upside down.

The Visor fits in the Rhodiana very snugly, and when inside, there's a quarter inch of case that acts as a rim and offers more protection should the Visor fall while the case is open. However, this rim also has a downside. It makes it difficult to press the power button with your finger. You'll probably find yourself using the stylus to hit the power button, or you'll use the application buttons to turn the unit on. This is the first of a very few gripes I have with this case. The case adds very little extra size to the Visor, and you can still slip it into a pants pocket with no problem.

The belt clip is okay and is very similar to the clip on the RhinoSkin ShockSuit. However, I didn't have any of the problems with this clip that I did with RhinoSkin's. The button on the back of the case is a larger plastic button that's placed in a very awkward spot.
