Those are the only two colors that the previous model (TU120XW) came in.

Black was added to the new (in May) 200 series.

I found out some differences; the 100 series is a little heavier due to a thicker and stronger frame and the 200 series is a little more rounded at the top.

Other than that they are virtually identical and from what a luggage salesperson told me, the 100 series is probably more durable due to the better frame.

For $129 it's a heck of a deal.

I picked up two while there.
