I want to add a screen door to my entrance...

It would improve ventilation and I wouldn't need the AC, but I'm worried about bugs getting in, not just when it's windy, but even when it's not that strong. I've looked for good products, but it seems like there are a lot of fake reviews and I can't find anything good. I don't need it in winter, so I'd like to be able to slide it to one side, but it's over 10,000 yen, which feels expensive, so I'm hesitating. Hmmm, I wonder if there are any good products...
