I have the Boxwave Flexiskin and so far I like it. It comes with a hand strap and a lanyard which is nice but no real place to attach it that I could find. I just looped it in between the hole for the speaker and one of the three slits on the left side.

It's not sticky, doesn't attract dust. I sometimes take it off and wipe the Treo and the inside of the skin down as I get a lot of dog fur trapped there.
