Yup, the RT-AC1900 (TM-AC1900) is a re-badged RT-AC68U. Runs VPN well for a very reasonable price. If you find a used TM-AC1900, look up how to hack the BIOS to turn it into a fully-capable RT-AC68U. They are exactly the same hardware, and the TM-AC1900 used goes for about $50 USD these days. Fifteen to thirty minutes of hacking saves you close to $100 USD. Now, if you want a brand-spanking-new top-of-the-line Asus router with hardware encryption, the more expensive RT-AC86U is a better choice. On sale, it's about $150 USD.
