Not sure if they’re still in production. There was also an Italian company selling one (maybe based on the same hardware).
Like u/floquant I would look at Mikrotik. But you’ll need to pay attention to port speed (they still sell 100Mbps gear) and their tested routing throughput numbers to be sure they can hit the numbers you need.
Courier Prime might be worth a look. Very compatible with Courier in size, but more readable and with a much less restrictive license.
