I have a 30GB Gen 3 iPod and have been waiting for the new cases to come out.

there is a few I have been looking at and although some of them have not been released I would like some opinions. THis is my first iPod so any suggestions and what will work well will be greatly appreciated

here's what I am looking at:

MacClear Zip (http://www.thinkdifferentstore.com/cgi-app/store/agora.cgi?cart_id=2725827.30692*dd6ZI6&p_id=654&xm=on&ppinc=search2)

G3 Jam Jacket (http://www.thinkdifferentstore.com/cgi-app/store/agora.cgi?cart_id=2725827.30692*HW7T25&p_id=646&xm=on&ppinc=search2)

Speck iPod Skin (http://www.speckproducts.com/index.html#)

These are just some of the cases I have been looking at. My ultimate goal is to find a case that will protect the iPod from surface scratches, belt clip, acess to top hold button/headphone jack, possible dock access? and hopfully a clear case so it can show the beauty of the iPod iself.

I know there are older gen users that have had luck with other older cases, post those thoughts here as well

Any thoughts would be helpful
