The B&R 4 wheeled bag is a good option for the roller. For the carry on also check Red Oxx, one of their bags is padded for cameras or Timbuk2 or Waterfield Designs. The latter has a new backpack called a tech backpack I think that might work. All of my Waterfield design stuff is stupidly over-engineered, designed and built. Made in the US as well if that matters. They also have great customer service (as does Red Oxx).
