Original 20% off Selected Stores on eBay deal
Not the cheapest price ever for the R7000 but hasn't been under $200 delivered for a couple of months.
Also possible to make an offer - I had $230 declined but $240 accepted so $192 delivered with coupon.
Similar to the Asus but with a faster CPU. Both have good support for third-party firmware. R7000 has Xwrt-Vortex which is a port of Asuswrt-merlin on the RT-AC68U.

If you're looking to flash Tomato, do note that the latest revision of the AC68U (C1) is not supported. And QoS on stock/merlin is pretty broken (outside of adaptive, which doesn't give you very much control in terms of rules/priorities). DD-WRT works on AC68U C1, but it doesn't look as nice as Tomato or stock/merlin and it lacks individual device bandwidth monitoring.
