My husband does close to the Belchertown to Cambridge commute a few times a week and it really isn't that bad. If it dropped to once a week we'd be sitting pretty. Honestly commuting around Boston is such a shit show you don't actually loose that much more time, he's only getting home like 30 min later then he was when we lived in Acton and our money is going siginificantly further. The biggest thing is having a workplace that is flexible on when you arrive/leave to avoid the worst of the traffic.
