If you have to pay for it out of pocket then I probably wouldn't as a couple years work experience with a Bachelors is more or less equivalent to having a Masters as far as most companies are concerned. If you're thinking it would be a stepping stone to an eventual PhD you're probably still better off going straight to a PhD program or perhaps taking MS courses part time while working and applying to PhD programs.
