As do I...but mostly because I don't trust the stock firmware being on my border router (port/protocol forwards have mysteriously closed on my G1100 before). So I have an OpenWrt device as my WAN. 
There's another issue...do you use FiOS TV?
There's traffic that occurs on the MOCA bridge, and the G1100 uses newer coax frequencies (channels) there wren't available on older MOCA equipment. This means you might have to purchase a newer MOCA bridge if you need TV.
Are you willing to open it up and search for a 4-pin TTL serial port???
An SSH server can also be enabled on this device...but using serial, we can look at the bootloader from power on.
We need to determine mainly:
- CPU
- Memory
- Flash Chip
- Wireless
- Switch Chip
Photographs are good too.
