So whether you buy or build, your bad luck will continue until you figure out what else is wrong and correct that.
The OP sounds like the situation I was in years ago. Bought a bike and wheels would last about 3-4 months. Then spokes would pop and the wheel would (naturally) twist.
As a learning experiment, I replaced just the spokes on my latest wheel failure... as the rim by itself seemed true and the hub was OK. I decided to read up on wheel building, buy a few tools and put together a wheel on my first attempt that lasted several years.
Maybe the OP is looking for encouragement to get into wheelbuilding. If he/she has the time and energy, might be a satisfying way to solve this problem.
