Bought during the special edition promo, the owner include extras for not much of an extra cost.
Beam Central Vac Special Edition
Power Q accessory package ($579 value)
Power Brush (for stairs and couches)
for around $1300 (tax included) installed. Install %50 per connection (got three) and $75 to hook up in garage.
Install is not that hard, but I am lazy and like to give my money away for other people to do stuff for me (according to the wife)
