I've grown interest for the Sterling Pacific, even more now as they lauched the 40l spinner version. By far the best looking of all options out there but so is also the price... I've read that they are sold in UK, France and Germany but none of the retailers have a decent webshop nor show them online. Warranties in EU might therefore be difficult to handle, which might still push me to stick to Rimowa, which has a store in my home city.
I also have the Lufthansa Alu collection, which is a great piece of luggage for the price. Sturdy, rolls nicely, comes with extras and seamless telescopic handle. The seal, however, is not perfect but it's not a deal breaker for me. I might even get it replaced by contacting Worldshop.
Another great looking trolley is the Piquadro Alu 4-wheel.
