davis_square | Hairdressers suggestions

I'm starting a new job on Monday - in fact that would be my first job ever, and I wanted to do a more "professional" look - after years in grad school:). This would be the second time I cut my hair in the US, so I have basically zero experience. First and last time here I went to Salon CU and saw Summer for highlights/hair cut. It was OK but I wasn't really thrilled (maybe because she didn't really talk to me much so I felt kind of awkward). Also, it was rather expensive (I think I ended up paying 100 with tip)... So, I'm looking again for a place to just cut my hair - and maybe style it a bit for a reasonable amount of money where they wouldn't screw it up. I have mid-back long hair and probably would want to make it about shoulder-long or a bit longer.
Thanks so much and sorry if that's been asked here before (I did look at the "hair" posts though).
