I built my own DYI prompter and I’m very happy with the effect. I bought a 97 dollar piece of beam splitter glass from SEETHROUGHMIRRORS.com. I’ve positioned a monitor flat with the glass angled at a 45 degrees above it. The results are awesome. Now I’m trying to figure out how to quickly and efficiently flip powerpoint slides so you can read them properly.
If budget is an issue…make your own. It works great.
