If the hub is good which it should be if the brand was good in the first place, then you need a new rim (they wear quickly) and spokes, install them yourself, all you need is a spoke wrench and to follow some generally available instructions. Building wheels is not rocket science. you need to find some online instruction that teach you how to pre-load the spokes.

New wheels would probably solve your problem, but they can also be just as badly built as your Fujis. If you bought your bike from the same store offering to build your wheels, they are already implicated. On a touring bike they should have checked the spokes going out the door, or they aren't for real.

While you have the wheels off the bike, re-grease and bearing the hubs. Another few dollar repair that gives you a new bike.
