Single digit milliseconds. Unfortunately anything ethernet over X will have latency due to the underlying medium.
I don't recommend Actiontec, I had a fairly expensive adapter go bad on me after about a year. I replaced the other ones with Motorola MM1000, which are much more reliable in my experience, and I found for $60.
Thanks, I saw some references to the Motorola, and I've had pretty good luck with their gear in the past (15 years of Surfboards after a cable tech recommended it as having fewer issues than the others). But when I searched pretty much all that came up for my string was the ActionTec.
