I just recieved mine this week on a closeout from Amazon/ebags:
Columbie PDA case
$9.99 USD with 4.99 shipping. I saw one of these last summer for $30 bucks and thought it was too much, but at 15 bucks it's a steal.
Both a carry loop and velcro belt loop in back (works better than you think). Has two pen slots on the side, a quasi seperated main compartment (little lips on the inside to keep stuff seperate), with good padding against the back and front, bound elastic on one side, and zippered on the other to expand.
It nicely holds Either: Axim/spare battery/CF/CFwifi/earbuds with room to spare for my Moto v60i if I wanted (but I like the v60's belt clip too much). Without the phone, you could easily get a sync cable or other accessories inside.
It cannot hold the Dell keyboard, but that wasn't a requirement for me.
Or it can hold: Visor/Stowaway/memplug/spare batteries (very snug, but servicable), take the stowaway out and I can put my sunglasses and phone it with much less bulk than the keyboard.
Seems quite sturdy, and less obtrusive than the other cases I was considering (i.e. not OBVIOULSY a PDA case). A very good knock around case for those of you who like to use your Axim
au natural.
For PDA free (i.e. gym days) days, it can easily hold my sunglasses, phone, wallet, and keys with room to spare.
