I currently run two fibe 25 lines (with a cisco dual wan router that combines the line speeds to give me 50/14). Since I've been a customer for awhile, I was able to get both lines, with a free modem rental, and their extra bandwidth (40gb*3 i believe per line) for about 59.95 each for the next 12 months. I'ts not too shabby really.
Only thing with the dual wan router, i had to get an older version traded in at cisco for the latest hardware version (v3) because it was giving DNS hiccups every few minutes. Once the replacement arrived, web surfing has been smooth as butter.
