I have 2 for my 30GB X5L -- the MisticAudio, and a Timbuk2 which is a universal fitting case that happens to fit my X5L perfectly.
MisticAudio:
Good-
- Good quality leather and well constructed.
- The stiffness of the leather offers good protection from falls.
- A "play-through" case - meaning you have full funtionality available while it is in the case.
Bad-
- It makes my X5 is too thick to have in my pants pocket and do any kind of walking or commuting.
- I'm always afraid that I am going to damage the joystick when inserting the X5 into it due to the stiffness of the leather and the snug fit.
Timbuk2:

Good-
- Excellent quality ballistic nylon with a very soft plush interior.
- Soft, so it protects from scratchs, but offers less protection from drops.
- It has a pocket in front that can fit the subpack and/or a pair of ER-6s etc.
- Great fit for either the X5 or X5L. Since the sides are elastic, it can be used for many other devices of similar dimensions.
Bad-
- You can use (listen to) the X5 while it is in the case (straigh or right-angle plug) but you cannot access controls. I usually listen to playlists while commuting, so for me this is not too much of a problem.
In the next month or so zCover
http://www.zcover.com/products.htm is supposed to come out with a silicone case for the X5.
BTW - for screen protection I use these -
http://www.pocketpctechs.com/ Quality screen protection like this is expensive, but it pays off. I have had the same WriteShield on my Dell Axim X5 Pocket PC for almost 2.5 years! And I use it extensively dozens of times every day! They sent me 2 (for ~$25) so I cut my spare down to fit my iAudio X5 screen. I'll never have to worry about it.
