Hi...our current set of suitcases is starting to split at the seams. They've lasted a very long time, so I can't complain. We've decided to use some Christmas money to purchase a new set. So, I'm looking for your recommendations. We'd like to keep the cost around $300 if possible, but since we haven't bought any in a long while, I'm not sure if this is realistic. We definitely want a wheeled set that the wheels can move in a circular motion, not just forward and back. And of course, durability is the most important feature. Thanks in advance for your help!
