My standard implementation for SMB is Mikrotik + Ubiquiti Unifi. The Mikrotik product line is comprehensive, from the smallest low-to-medium bandwidth solution (various MIPS-based routers) to high-performance multi-1G (Tile cell chips in their CCR line). It's amazing what you can accomplish with a $100 router: VLAN, every VPN tunneling method you can name (and some you can't), MPLS, BGP. I use them as remote office VPN tunnel routers, set them up for L2TP so I can do remote support, use packet mangling/traffic shaping for VOIP. All this on a $100 router.
