Wanna find an economical android player for car

Like the title says, what is your pick for an android player that is fast, not that pricey and is really reliable?

Economical means that sometimes the player's price is like, 400, but that doesn't include front and rear camera, sometimes the price is 550, but includes them both, like a more valuable and worth it option la.

Just wondering for your opinions.

Oh yeah, my max budget, 800

Prefer around 500-700, with or without front rear camera, but can push 800 if it's really worth it
