Good luck. The official Amazon cases (with or without light) are definitely overpriced, at least in the UK.
I don't have a kindle but I wanted a little pouch for my palm pre and offered to pay her so that I could be her first customer but she wouldn't take my money smiles. I'm sure she could make a business making little bags for the various gadgets we have. I was thinking I'd make a page where individuals could make custom size requests for little bags for their gadgets.
Thank you for the comment.
That said, the OPs cases do look good and appear to be good value for money.
