Couple more things for you.
How much is the latency (milli seconds) between your home and the broker's servers? Latency is for trading often more important than throughput speed.I live in Singapore now and I get 1 Gbps (1000 Mbps) on fiber for less than US$ 30 a month.
This is cheaper and faster than the internet I get in the States.
I scalp, so speed is everything.
