Larry to be honest i know you have decent knowledge in OS and software so you should be building your own router.
Seriously, once u build one, you can never go back to commercial unless its for someone else or u want something very dumb'd down for the user.
A very low voltage i3, or pentium G, like one of those 35W, with 4-8Gigs of Ram, with a ITX board and a intel nic.
Or something like this:

Then install Pfsense on that system and go from there.
That is a super router... You just need a switch to finish it off.
Hammer it with torrents... no problem.
Hammer it with users... no problem.
Need VPN tunnel, no problem.
Need Squid to monitor what is trying to hack your network... no problem.
Need to monitor bandwith no problem.
Need to log who is downloading what? again no problem.
Need Wifi? just connect an AP on the switch below.
Want something super stable that has uptimes for months.... Build one of these...
This is why once u get to the nicer enterprise class, you just really dont want to go back.
