For those who are atleast in the USA. The kindle covers and cases are practically a perfect fit for the Archos 7HT.
Best Buy is a major chain in the U.S. which carries a few varieties of theses cases (hard and soft) I trialled fit them and works great for nice cases for the tablet. Some of the ones they carry that can be found on Amazon or other sites are listed below. I only mention this because it is nice to go on a road trip with your Archos 7HT and actually look/touch/feel a case to see if it really works for what you want versus an online purchase.KensingtonLattitude JacketSoftsuit
The kindle cases were very sexy, but failed to provide any storage for anything, except the tablet itself.
So I actually settled on the Soft shell case by Embark Deluxe Travel Wallet
below. It is kind of funny though 8-O I didnt think I would actually use a travel wallet for the purpose of a Tablet case but for my needs this works very well for me.
The wallet has several pockets that I can use to store my usb cable and SDcards, headphone ext cord etc., Also the case comes with a zipper to close it all up and a finger strap on the outside for easy carrying. A couple things I did to modify the case a bit was place a felt liner for the pocket the Tablet rests in and a velcro strap from the spine of the wallet to the inside of the pocket for the tablet to prevent accidental falls.
It is not the cleanest job (I am not a sewer) but this is very practical for me since I travel quite a bit, something robust and versatile so that everything I need is in one place is what drew me in to this case.
The price was good too! under $15
