Usually my luggage is whatever I can get my hands on and its not too expensive.
Currently I use a Burton Flight Deck for my carry on
Liked it so much (especially since I got it for cheap) I picked up the double deck for longer trips
I'm sure theyll both hold me over for quite sometime, and when they finally give up the ghost for sure I will finally invest in something from the Rimowa Topas line
^roughly 1k, whereas both of the burton bags were under $100 each. yikes
