I guess I should have said, cheap and very inexperienced with all of this. If $60 gets the job done, then I will gladly cut my teeth along that route. Thanks for the suggestion though, I looked it up and the first couple pictures I looked at made it seem like this would be much more difficult than configuring the built-in VPN of a new router. Maybe I'm wrong though.
Consider the Asus RT-AC68U... It can be had for $100 or less. There's a TM-1900, a TMobile variant which can be flashed (even by a newb) to function 100% identically to the stock Asus RT-AC68U - and those can be had for sub-$50 when on sale.
I recently flashed mine to the Asus-Merlin fork (which is a much more capable version of the OEM firmware). Either stock or with Merlin, the OpenVPN server that is built in makes it stupid simple. Rather than having to create custom keys and certificates, it does it all for you. With stock settings, you click one button and it creates an .ovpn config file that you import on the OpenVPN connect client (the software you run on a PC/Android/iFruit), and it just works. It allows you to hop onto your local network from anywhere on the web. It is so easy to do, I was able to do it (and I am an total VPN greenie).
