My comments below are just my opinion and in hope Brent learns more about the product.
"JAP Cons Requires expensive Network Switch Requires good quality termination practices Expensive System Price Large(ish) unit size"
Luxul and Cisco both make affordable swiches that are much lower cost than you think
Any network requires good termination practices. A dealer who cant terminate an RJ45 connectors shouldn't be installing AV gear.
When you are talking a small size system yes JAP is very expensive. Keep in mind though when you add all of the additional features that JAP does there is a cost associated with them and its sometimes easy to let a price tag make you forget about all of the things vwpower listed above.
Im not sure their units would be considered that large. I havnt had any dealers have issues placing them.
