Mikrotik makes some very capable routers. The Rb4011 is incredibly powerful and very low power, and has an SFP+ port, so you can use a sfp+ to rj45 if needed, or straight modem -> sfp+ connection, to get faster than 1 gig speeds.

It has a steep learning curve though, albeit it's extremely rewarding and powerful once you gwr over that curve. It should handle routing 1 gig with zero issues, and is under $200. You can do bonding, vlans, esoteric ip rules, and tons of "misc" functionality.

Do not go with ubiquiti, their hardware is very poor and their UI is very buggy and simply poorly designed, it's focused on people who know a bit above an average person about networking, which I suspect is not the case for most people here.
