I have no knowledge, but my gut tells me that someone busting their butt to stand out is someone I might want to be associated with.
If it's a piece of paper from MIT/NW/etc. rather than U of Phoenix (not hating), I'd pay attention to it/you in a different way -- I'd say, "Oh, you're upper-class, you're one of us, therefore you're a safer hire".
Then again, I wasn't raised upper-class, so I don't know if that's actually how upper class people think when they hire, but i met someone recently who, when i said my most enjoyable job was at a startup in Palo Alto because everyone was _really smart_ and just _got it_ -- he was like YES!
It was like, he wanted to be around winners - high achievers - or at least people who were well-born - that's how I took it, anyways.
And so I suspect spending that relatively tiny bit of cash would be 'worth it' -- probably x10+ within 10 years in pure monetary ROI. And plenty of intangible benefits.
There are people who think school/uni is about learning. That's fine.
And there are folks posting to HN right now saying MBAs are worthless. Ok.
I'm actually surprised you'd be able to spend that little on a cert, but I guess there are all sorts of certs, mini-certs, programs, etc.
I suspect it would actually be pretty fun if you were actually interested in the material, or at least interested in finding out if you were interested in the material.
If you're lucky, if you can control your diet and not have too much bad luck, you'll probably live to 100. So, spend the cash. That's my take.
And make friends with the people in your classes.
