I have a DSUSB unit that I purchased a while back that is surplus. Same as this:

Used to trigger your DSLR from a laptop, cable allows you to use it with Canon cameras that use the 2.5mm plug rather than the N3 plug.
Works fine, just don't need it and need $$$ atm to part fund some new stuff!!
Now $80 for the DSUSB and cable (was $100) these together would cost $129 + $19 or $148 in total.
