I ran across MikroTek after it was mentioned in a thread on smallnetbuilder. Having never heard of them, I find myself impressed at the price/performance of the routers. 
So now I want to know what I need. I have several site-to-site VPNs connected currently by Cisco and Netgear small business routers (rvxxx and fvsxxx series, respectively). I’ve been considering changing them to the Zyxel USG series for the ability to aggregate WANs for failover and increased speed of the VPN links.
What hardware would perform just as well in the MT line? Thank you in advance for any answers.
