Pilot Luggage

I've got a luggage question that I'd like feedback on. If I'm going to spend about $400 on a roller bag which option makes the most sense:

Purdy Neat, which is the cool pilot bag to have

or

Brigg & Riley, which is a foo foo bag that more expandable than the Purdy Neat AND has a lifetime warranty, no questions asked.

I've looked at the Briggs & Riley and "collapsed" is it the size of a normal roller bag and will fit in the overhead. With the flick if a handle, the thing expands to be another 4 inches deep.

The unconditional lifetime warranty is what has me thinking about it, whereas the Purdy Neat is warranteed against manufacturer defects.

Feedback anyone?
