I'm considering buying the Traveler's Choice Amsterdam 4-Piece Set (eBags Link ) or some pieces at Costco for travel with the family. This is a great deal for 4 pieces ($99.99) but I've never heard of Traveler's Choice before. Should I go with Traveler's Choice or stick with what Costco has to offer. We're primarily interested in larger pieces of luggage to check for 5-7 day vacations. Thanks!
