Bill,
I really like my Turbo 2+ --- I bought the black one since it would probably match any other bike I might buy in the future.
I did opt for the roof rack - you can put up to 75LB on it (think big bag for jackets, rain gear, sleeping bags, pillows, or other bulky stuff).
The Turbo 2 is a little lighter than the quantum but almost the same size.
You may want to consider getting the Street Glide tail piece with light to cover up the hitch -- it is black and would match. You can also buy plugs for the street glide antenna holes that are in the tail piece. In addition, you may want to order the LED tail lights for either trailer you choose -- they are much brighter than stock and draw less power.
If you want the trailer quick and you decide on not getting matching paint - you can order one from Rod's Power Sports
http://www.rodspowersports.com/ They keep large supply of Bushtecs in stock and all the accessories. (Same warranty and price as Bushtec). The Buchtec guys were backed up and couldn't ship one to me in time to go to Sedona - Rod's shipped mine the same day I called.
You will not believe how well a fully loaded Bushtec rides -- you'll have plenty of room for all of Anne's hats!
