I have a simple Dlink dir 600 with DD-WRT installed. It works for my PC, laptop and mobile devices.
I'll consider upgrading to an AC router when I have better internet.
For me the most important requirement of a router (or any device) is that there must be a modified open-source firmware available. I mean, what kind of 'techie' are you if you are running a stock ROM on something as simple as a router?
When its time to pick a new router I'll check Amazon reviews, then cross-check it with the compatibility list for Tomato or DD-WRT
