The vaja ones are good. But keep in mind...if you put pressure on the clear plastic cover it will put tiny stress cracks all over it. It will make the screen look a bit fuzzy over time.
If you really want one at a discounted price...I have a bunch for sale in the forums... WTS: A bunch of 8700 series cases... One 7130c Case - see inside.
Sorry about that...but I am desperate to sell them. ;) I hope you find what you need!
Also, check out the review forums, you will see a bunch listed and reviewed.
