Teleprompters are not a one-size-fits-all purchase. The cost of a teleprompter will vary based on the size and type of prompter you need. For example, a small handheld teleprompter for use with a smartphone might cost around $100, while a professional-grade floor standing unit could cost upwards of $5,000.
When considering the purchase of a teleprompter, it's important to factor in the purpose you need it to serve. If you're only using it occasionally for personal projects, then a less expensive option might suffice. But if you're using it regularly for professional work, then investing in a high quality unit will pay off in the long run.
No matter what your budget is, there's likely to be a teleprompter that meets your needs. With some careful shopping around, you can find the perfect prompter to help make your next project a success.
