I've only tried the Invisible Shield so don't know how the other ones are, but here are some other brands of full body covers similar to IS. I'm not even sure if they sell one specific for the HD, but here they are:
Best Skins Ever
Bodyguardz - compared to IS or BSE, i've read this one is thinner, clearer, has less self-healing properties, has less grip, is slicker, has less-orange peel look
From what I've read, IS seems to make the best ones as far as quality and cut, however, I did end up returning mine. I think no matter which one you get, you're gonna have some general annoyances like corners not being completely covered, rubbery feel, bubbles where the frame lifts higher than the screen, etc. I think I was just expecting too much and was thus disappointed.
