Hi and welcome to mobileread
For my Kindle 2 I used to have a Tuff Luv flip cover which had a stand built in which was awesome - I used to prop the Kindle up by my PC so I could read and blog etc.
As I now use the lighted cover (not swapping that!) I use a simple plastic book stand which just happens to fit well when I need to prop the Kindle up - normally while in the Kitchen.
Anyway there are a few options for you.
