I know there was a thread recently started about a new third party grader (Verisleeve), seems like this is another new one I haven't seen before.

From their site:
ISA storms the hobby taking in ten times the amount of cards projected in opening week! Jason Koonce, owner and senior grader of ISA said, “We knew that we had support from numerous dealers and auction houses, but we were still shocked that we brought in just over 17,000 cards for grading in the first week of business. If we continue to gain respect from the collector, the person we care about the most, there’s no telling how big ISA can become.”
Personally I more or less exclusively use SGC and that most likely will never change, but I do find it interesting that more of these fly by night companies are popping up.
