Hi,
you tell us what you want in a bike, and then we wll have a better idea. The 520 is a great bike for the money. There are lots of other bikes. If you don't plan on carrying a tent, I would say take a long look at light touring bikes, there are many.
If you want to ride across the continent, I would say something a little more rugged. The 520 certainly could do it, it's a rugged bike. But if I was going to live on a bike, I would get a Waterford or similar. It all depends on what you want.
