I definitely would not go with Lock. They do not pay people their money from what i have read.
I have spent the last two days researching the poker sites that allow United States players, and the ones I liked the best are Bovada, Carbon, and AmericasCardroom. I downloaded all three softwares and played on each with PLAY money. I like Bovada the best, and will try to make a deposit in the next few days. They are all outside the jurisdiction of the DOJ. And I know Carbon and Bovada do not have .com address, which means the DOJ can not seize the sites, at least I think they can't.
So far, it seems Bovada has the most traffic, at least for the SNG's. It looks like their traffic is comparable to the early days of fulltilt. Probably 2000-5000 users on at peak times. I will try multi tabling their sng's, but I don't know if they have enough traffic to make it worth it.
Thanks Everyone for the info, and I will continue to report back on my experiences with these companies.
