Looking for an inexpensive teleprompter

I have been doing a number of training videos for work lately and I think a teleprompter would help cut our shooting time by a bit. I see a few options that include using an iPad as the teleprompter for around $110 with the software. Does anyone here use a teleprompter setup that's affordable and that can provide some feedback on what I should look for? Thanks in advance.

Check out prompter people. We use their cheaper setup at work and it has worked great.
