Yay! I managed to get myself a 3849B028! I placed an order online to make sure I at least get one, but when I got to Micro Center, the one they put aside was C0, so I went to the display glass and asked salesperson to check a few there, first one was another C0, then the second one he got, it's a D0 and B028, exactly what I had in mind to get. The sale is over on the 22nd. I might go back and get a few more of different batch, test them all and keep the one I like, sell the rest.
