Sorry, I got your moniker mixed up with markrdee who has been giving me a hard time. My fault.
The differences between the Neo and the MkV are huge. One weighs about 20 pounds and the other less than one. One has the motor on the top and the other has the motor on the bottom. One is made from solid slabs of 3/8" steel and the other is made from sheet metal stampings.
This is definitely a case of living off the image that was (justifiably) created. The first two Neos are works of art. Everything else is just a pale shadow. Take a close look at the linked photos and you will see what I am talking about.
