I've got a Mikrotik RB4011, and I couldn't be happier with it. It definitely has a learning curve, but once I got it setup how I want, it just works. I'm sure some other options have the same feature, but one of my favorite things is a script I have run every night that emails me a backup.

I've only ever had to use it a few times, but having a recent backup of my router on hand all the time is nice.
