I've used Apartment Rental Experts (http://www.apartmentrentalexperts.com/) in the past and have been very happy with them (disclaimer, I'm a landlord, not a renter, but my tenants seem to have been pleased with them as well). They don't cover all the areas you list, but checking their page today, I see the following list:
Right now, the only 1BR they have listed for under $800 ($795 including heat) is in Malden, which is not on your list, but presumably more places may show up in the next few months.
