Hoodman Loupe and other similar products

[gossamer]

Hi,
I purchased a Hoodman Loupe some time ago to help see the LCD on my Nikon D300 more clearly and hope to block some of the sun glare in bright environments.

However, it's larger than the display, so it doesn't quite fit properly, making it necessary to adjust it for the particular section of the display I'm interested in seeing. It has to be moved out of the way to access the menu, zoom in/out, and other buttons down the left side of the display. It covers them, making the loupe difficult to use.

Are there other similar products that offer better features and are more closely suited for my particular camera?

Thanks so much,
Dave
