The Hecto doesn’t seem to come with the screen, does it?

It does not come with the screen.

Then it’s pretty useless. It needs a special screen, you can’t use regular projection screens, and I have no idea where you can get the screen alone.

I bought one from woot last year, just project to the wall, it works very well. The image looks better than my previous LG led projector.

It does not require any special screen. You can use to a screen if you want to get the best image quality from it, but you can project this onto the wall with no issues.
