What are your needs?
Hard to provide some options for you without knowing what your needs are.
Some advice...a UTM appliance, if you work on infected computers...helps make your work easier because "bad traffic and requests for payload downloads" coming from infected computers can be squashed.
Don't forget you can build yourself a UTM firewall for cheap...even free, using old x86 hardware and an hour or two of your time. For a computer tech, often no excuse not to have one...even if the words "but I can't afford one yet" are muttered.
^What he said.
Take an old P4, or Atom, or Celeron.
Toss in a couple of NICs.
Install - Enjoy!
I'd look more at Untangle and Endian (my top two pics).
If you decide Endian, I'll give you a hand with configuring it if you'd like.

If I got it, you can use an old machine with proper software n a couple of nic's and it can replace your standard router?
