Here! Here! CJ!
TQS is Bernina sponsored, other shows and sites are sponsored by other brands. They tend to much more brand specific that I have seen.
I think TQS does a good job of using the brands that they are comfortable with (both Alex and Ricky are Bernina owners from way back) and recognizing that not everyone has that machine. They do tell everyone to check their machine for specifics.
My original machines only had the straight stitch, all I ever felt was envy for those that had a machine that could do a zig zag.
Alex and Ricky, to my knowledge, have never appeared on TQS and tried to sell Bernina machines.
