My bike was breaking spokes like mad on the stock wheel. I bought a whole new set of spokes and a better rim, and rebuilt it myself one evening. It ran 13,000 miles with zero maintenance after that, until I broke an axle. Never went a mm out of true.

A good wheel doesn't really need regular maintenance, only a tweak if it goes out of true.

Sounds like the OP's spokes are under tensioned, especially if they're breaking at the elbow.
