You can get it for $402.10 if you're quick here https://vi.aliexpress.com/item/1005009200866887.html
Newest version of the Lenovo legion y700 series on sale. Notable improvements are the 3040×1904 resolution screen, snapdragon 8 elite processor, return of SD card slot as well as an increased 7600mah battery, up from 6550mah.
Not OLED like the redmagic astra but it's more expensive at $520 for preorder.
Edit: iota pointed out a $50 off $399 bringing it down to $399.
I wish all the Redmagic tablets were Lenovo-affordable. They make some tablets.
