Asteralice.com has an extra 25% off with code new2011. I just used it and got the rm teal croc iPad case as pictured above.
Hardcandycases.com also has some neat cases. Got their bubble case, and the jelly sleeve (fits inside bubble case). The bubble case offers a lot of protection.
I'm not sure if this qualifies as a case, but I am completely in love with my Lap Log. I also have the regular Apple case, and it fits perfectly in the Log without having to be removed. It honestly changed my iPad experience so much for the better, I can't recommend it enough! (and no, I'm not affiliated with them at all, I just love their product ;-). http://www.thelaplog.com/
When I bought my iPad back in April, I had the clear belkin grip vue but now it's yellow and disgusting. It looked great and fit perfect at first but the discoloring bugged me so much I had to get a replacement case. I ended up hunting down the speck candy shell case. There is a flap that opens up the dock port and allows you to dock the iPad with the case on if you have the iPad dock or iPad keyboard. I love it. It's cushiony inside and hard on the outside to protect the iPad.
Check out switcheasy, I don't own an iPad personally, but I've used their cases for my 3G and iPhone 4, as well as my Nano, and They hold up well, come with a hefty amount of pack-ins (screen protectors, dock connector covers, etc.) and are priced reasonably.
Some more RM iPad Cases!! This time it's from her Men's Line, called Ben Minkoff. This one has a zippered top so you can just slip your iPad inside, unlike her other cases where it opens like a book. See pics below.
CAMO (also posted the iPad modeling pic on the right..)
Blue/Green & Black
Saks.com is currently carrying these iPad sleeves for $135 and $165. The Blue/Green & Black cases are made of canvas, and is priced at $135. The Camo version however, is made of leather and is tagged at $165. These might be a good alternative since her other iPad cases are quickly selling out. But since these cases has a completely different opening than the other cases posted here, I'm not sure how convenient it is. Enjoy.
