But as I mentioned back then, its strongest competition comes from Vizio's other models, which are now cheaper and more feature-packed. The standard 65-inch P-series is now just $1,300, while the 70-inch mid-range M-series is $1,500. If you're looking for the best that Vizio has to offer, the Quantum is your best bet. But if you're looking for a good deal, you've got plenty of other options as well. You'll find the P-Series Quantum at retailers like Best Buy, Sam's Club and Costco today.
