Almost all Bangladeshi conglomerates assemble or manufacture rice cookers. Even companies as small as HAMKO (who are essentially aluminum non-stick cookware makers) have their own Rice-cooker line. They must, everyone in Bangladesh eats rice with their meal.
However there is quality difference per price. Some higher priced ones have non-stick coating. Other ones sold in Japan and Korea have some kind of stone coating which is even more robust and where rice never gets burnt. Temperature adjustment of the rice cooking process needs to be carefully calibrated and regulated for all rice cookers, cheap or expensive.
China makes a wide variety and different qualities of rice cookers per market requirement, there are thousands of different types. Their expensive stuff is quite good, but they don't sell under name brands in the US that I have seen.
Of course Zojirushi is the best in Japan and some of their expensive models with pressure function sell for around $300-$400, some of my "shoukhin" friends have them. I am happy with my $50 Panasonic model, cooks rice fine.
This top-of-the-line Zojirushi Pressure Induction Heating Rice Cooker & Warmer uses pressurized cooking and AI (Artificial Intelligence) to cook perfect rice.

Korea-made ones ("Cuckoo" brand is one) are almost as expensive as those.
In Bangladesh the best brands are Vision and Walton. Now rice-cooker brands, types and sizes are so many in Bangladesh, it is pointless to import rice cookers from overseas. These things are found even in corner "Mudi Dokan" now and are disposable items. If the price is low enough, you can throw one away in two years and get a new one.
