I thought long and hard about a Guard Dawg and still haven't decided. One of the biggest assets (and a large part of their marketing) is the keyless convenience of it. With a Vision, that is greatly diminished due to the fuel door and locking storage. Less so with the storage, but the gas cap is used pretty routinely, especially on trips. So, you still have to have (and fumble with) the key. I was actually more interested in the convenience than the theft protection, so I guess that's why I'm hesitant.
