Given the current Japan Post situation, what are the best options for shipping to the USA?

So I'm trying to liquidate extra photo equipment I've got, and a lot of potential buyers are located in the USA. Can't ship by EMS like I usually would, and haven't shipped to the USA with other services like DHL.

If you have recent experience shipping packages to the USA (shoebox size, basically), I'd be very interested to hear your opinions on what the next best thing to EMS would be.

Thanks!
