Why would anyone buy a unit that is not SFI rated and will be rendered useless in a year or two. NASA, PBOC all require a SFI 38.1 unit and SCCA is soon to follow. Buy one that meets the requirements and be done with it.

If people would stop buying the NON SFI 38.1 units now they would be forced to make a choice. Go out of business or redesign theirs to meet the requirements.
