Throughput is not important really. Any DSL or Cable Modem package would have sufficient bandwidth for trading. Latency is more important, but generally speaking DSL and Cable Modem have similar latencies. If you have FiOS in your area, that would be the best choice for latency.

A leased line isn't going to really get you much over DSL or Cable Modem, except a bigger bill. Your money would be better spent putting a server at a datacenter near the exchange if you have an automated strategy that benefits from lower latency.

I agree with BM... you can get a colo for around $100-$300 for a 1U server... however, a leased line will give you much better reliability as well as reduced latency depending on your location and how near the exchange you are ... cable/telco clouds will route all over the place before they connect to a given NAP within their network to travel to where you want to go.. there will be points within their cloud that will be slower than others, and that will add to your latency.. so if you get 100-200ms on average from cable/dsl/fiber you might, and I say might given that it depends on your t1 provider and your location, bring that down to 30-40ms... IMO it is cheaper to colo and then autotrade under <1ms... but if you are doing disc trading, then the leased line ($300 speakeasy in my area) is worth it because of its reliability... specially if you can get a 99.99 SLA for unplanned outages (52mins per year)... so when looking at a leased line or ethernet or fiber or cable or dsl... the evaluation criteria is not just bandwidth and latency, but also reliability.. IMO ... if you are trading PT, these things might not matter as much... if you plan to do it FT... they will matter as that will be your business.
