Oh, I forgot !
I also mounted a top box, spot lights, a lowish high screen, bigger mirrors, mirror extention brackets, cross bar for a phone holder, phone holder, and a smallish bag between my feet on the Agility.
I've also bought a light kit for the top box but the kit still needs to get installed.
I think these components will also get more expensive and some items might not even be available locally in the near future.
I haven't made calculations, but I think the total costs of all assesories on my Agility probably matches the initially price I've paid for the Agility. This does not bother me - I've bought the Agility at a very good price. Should I decide to sell, I think I should still get my money back.
