[Plextalk] What Plextalk Players can be purchased in the U.S.

Hi. I believe that I will be in the market for a new pleyer. What players that Plextalk makes can be purchased in the U.S. For instance can the linio Pocket be purchased in the U.S. If It can be purchased in the U.s. how much does it cost? Can you read NLS books on them? Where can I get more information on these players and where can I go to purchase one? I believe that my Plextalk player will be no longer usable. I don't want to get another Plextalk player because to me it's old technology where the firmware isn't being updated. Thanks for your help. I'm not sure if I want to purchase the Stream either.
