USB or RS232c port?
Here's one for $50 if you want to use RS232C

http://www.nostek.co.kr/software/mas343_345_m9803r.zipI have downloaded and run the setup.exe and it has an Excel button on the GUI to export the data as an export CSV file.
You could always get a USB to RS232c adapter if your PC doesn't have RS232c port.
or a USB model for $250
