or if I should try to find a good quality version instead, since what I usually find is in the supermarket where it’s almost universally cheap junk

Or take the opportunity to check the second-hand market for it! Craigslist/FB marketplace, thrift shops, ebay (used, private seller), garage sales, etc. Tends to be a lot cheaper, great for the environment (because less resources needed for new production and less stuff in landfills), and keeps your money away from evil corporations.
