Replying to Golfers of Boston

I know its the wrong season, but I'm starting to think about golf already and I'm hoping I could get a few answers here.

Spent the past four years at UVM and grew up in western MA, so I'm looking for some recommendations for relatively nice courses in the greater Boston area. I will be working in Copley Square and (hopefully) living not too far from there. Ideally, I would love to be able to leave work and go play 9 holes before it gets dark.

Starting in May I will be largely financially independent. I will be making good money, but I'd like to save as much as possible. I'm going to keep an eye on Groupon for some deals, but I know that golfing once or twice a week over the course of the summer simply won't be sustainable.

So if you have any recommendations for public courses within 20-30 minutes of the area that are reasonably priced please let me know!
