Howdy Dave,
Consider this, when I have been around a BGE, and lifted the lid, it's a bit of a workout. Not a huge deal, but think about opening your garage door, again not a huge deal, until you get an opener.
The KK has the equivalent of an automatic door opener (spring loaded hinge) No effort required, just release the latch and bingo, it's open. I just wanted to point out something that won't show up in a picture. But it's one thing that will benefit you dozens of times each use. Good luck with your decision, and if you roll this way, someone will show you the secret handshake!
