That is kind of a broad question there. There really are no good prebuilts in the $1000 - $2000 range. You either build your own or you're compromised with what you have. How much are you looking to spend?
If companies sold products at a loss, they'd be out of business quickly. If you mean finding a prebuilt cheaper than building it yourself then yes, but at the expense of quality and upgradability. I'm not sure what your budget is but you can find some vr ready prebuilts for less than $1k. https://www.newegg.com/Product/Product.aspx?Item=9SIA6V664V5920
