Not sure how this will be received by the H5 folks but I want to share a few things.
As of this writing, the store is sold out of Mark IV usb power cords. After loosing mine I did some digging, found a replacement, and have tested\used it with no issues (and it is a couple feet longer than the original).
Digi-Key Corporation - part number 839-1018-ND - sells for about $5
Also, you might find the pelican case that ships with the ultimate kit to be a bit too small for fitting all the goodies you want to carry. Ironically, my original ultimate kit was stolen so I had the opportunity to repurchase. I got another Mark IV and a few other toys but opted for the pelican 1060 (next size up). It still fits in my backpack but with a little more extra room inside
eBay - $26
