Look on the manufacturers website to find specific models and screen material choices. There are about a dozen or more models from each of the major manufacturers, then those come in a couple of dozen sizes (or more) per screen design, then those often have as many as half a dozen (or more) different materials that can be used to make the actual screen.
Think HUNDREDS of different screens from each major manufacturer with each one being a bit different.
Almost always, a screen under $100 will be a manual pull down screen. If you aren't getting a tab-tensioned screen, than the extra $300+ you spend on a motorized screen is what I would call wasted money. The screen will get waves, then look bad, then you are out the full $400 or $500 (or more) you spent. $100 can get you a manual pull down screen which will work just as well, but does require you to get off the couch to pull it down before you can use it.
If you have some that strike your interest, post a link to it and I (and others) can give you our opinion and feedback.
