If we could get an accessory section like other forums out there I could put all of the stuff I found so far into it. But we seem to be lacking here today (sarcasm).
Still Qmadix has a case/holster combo, Verizon has their cases and $20-30 is too much for what you get. Take a cruise on over to eBay and search for Droid 3 XT862. Okay I did it for you

So far Zagg has nothing on an invisible shield and no eta or IF they will carry one, of course they said the same thing about the Droid Charge and when they said they didn't offer one, I got one at Best Buy that very same day.
Watch out for the Verizon screen protectors, they do not appear to cover the entire display, I could be wrong but the image looks like it doesn't.
I did find Incipio makes some at Amazon for $7 or so.
Don't forget your microSD card, Class 10 is what is recommended for the 1080P video. Amazon.com has a 32GB Patriot microSD w/ SD adapter for $64.99 after $15 MIR. Not bad.
