It's the final day of Amazon Prime Day, and while we've already done a roundup of star projectors that are worth spending your money on, this guide is designed for those looking for the best budget models. This doesn't mean cheap and nasty, it means products that we have tested and think are good value for money, given their low price tags.
Star projectors can cost anywhere from $15 to $600, with prices varying in between. The cheaper models typically have more limited functionality than the premium models, but for the average person seeking a cost-effective way to transform their space, an affordable but good-quality model will suffice.
Here are the cheapest star projectors that are actually worth buying.
