How much are the bluerays and what is the best brand?

Sony

If you're talking about a blue ray movie 🎥 they vary in price depending on the release date and demand for it. As for brand, i personally didn't know there where didfferent brands of blue ray.

Or if you are asking about Blueray disc players; Sony developed the technology but they are manufactured now by many different companies. The prices vary on these as well, mostly based on manufacturer, but there is some variance owing to features and size. You could probably find a decent one for a bit under $100 now.

DVDs or TV that play. Blue ray. The movie range in price newer release are more expensive. The TV try to wait for a sales holiday.
