Ideas for a gift

[katepoet]

I want to get a rolling laptop case for a friend whose back is hurting from the bag she carries. She's not a backpack kind of a gal. I think the ones that allow you to take the wheels off and use it as a regular briefcase make the most sense. They seem to range in price from $40 to several hundred dollars. I need to stay on the low end. Has anyone tried one out? Any idea which hold up and which fall apart?

(Not sure if this is the right place to put this thread - sorry if it's in the wrong one - call it newbie-itis!)
