Which projector did you buy? What was bad about the quality? What technical issues do you have with the projector?

With regards to buying a projector, try this as a guide:

1) Budget. "Affordable" is not a number. Also, you get what you pay for.

2) Usage. What do you plan on using it for mainly? Watching movies? Playing games? Doing presentation?

3) Brightness. Are you planning to use it in a dimly lit room? Bright room?

4) Portability. If you want to set it up in one place, you don't need a portable projector.

5) Ease of use. Traditional projector only is easy to use; set it to the HDMI input and you're done but they often do not have speakers. The Smart Projectors have everything but making it smart sometimes dumbing things down.
