Thanks @baylinor and everyone else. Great info you are all providing. I was told by someone I trust that the output of all good streamers is basically the same - digital data so select a good one, but focus on the interface/reliability, features, app . .. He said the big differences someone like me will notice are in the DAC/AMP/speakers. Not saying there is not improvement with costly streamers, just maybe beyond my ears, budget, and beyond the rest of my system/room. Plus, I am of the belief (right or wrong) that digital data is digital data in well built and properly functioning system. Hence focusing on the software side of the streamer.
I am looking used for a 2i, but sometimes not that much less then new.
This forum is so helpful. Thanks everyone.
