With any new wheel you purchase, spokes will loosen after the first few hundred miles of use. This will happen to a greater extent on some and lesser on others depending on how it was built and by who or what.
So if your wheel is made of decent brand components. And after a few hundred miles you take it to a bike shop and get them to tighten and true it, then it'll last you quite a while no matter what you get.
I've found decent inexpensive wheels with a combination of mavic and shimano components. There are many others out there too. Google, as suggested by the first response to your post. You won't find any terrible ones. At least not if you look for name brand components.
