Same here milkdog... I've done the toolhead cable, oil absorbing foam, metal printing toolhead base and camera kit upgrades so far... and the videos have been excellent for them. I also had the silicon lubricant head fly off... obviously we're too impatient to let all that good lubricant come out in it's own time!
Only problem I've encountered so far is that whilst my camera now has a much better field of view in the vertical direction... it is rotated 90 degrees... just like someone else posted in the forum a few days ago... so off I go to add my name to the list of those inflicted!
Oh, and if you want to see what the difference is between the two cameras, have a look at the post I just made in that thread, as I have pictures from the stock camera and the upgrade kit camera. Ignoring the 90 degree clockwise issue, you can see the upgrade camera adds quite a bit of height to the field of view.
