If the weight of the actual trolley is the most important metric, then the Essential Lite Cabin is my recommendation to you.

The difference in weight compared to the Essential Cabin is 2.2 lbs (3.2 kg vs 2.2 kg).

Price difference in Germany is based on the Essential Cabin Lite, compared to the US MSRP:

Essential Cabin Lite
German MSRP: €400 - Global Blue VAT Refund (€45) = €355/$404.50
US MSRP $575 + 4% Hawaii Sales Tax ($23) = $598 Total
Total Savings = $193.50 (32% Off)

Yes, NOS are the discontinued models that the authorized dealers still have left over.

I was able to pick up a RIMOWA Titanium Topas 67L eTag for 51% German MSRP, last month.

The only RIMOWA flagship store is located on the first floor in the Abu Dhabi mall.
