Yes, I'd have to jump on the bandwagon and recommend the 135 job first. If they have turbine equipment, then so much the better. PIC Turbine time is where it's at. If they have them, to get into their turbine equipment ASAP, even if it means taking over a crappy route to do it.
As an aside, you'll also probably make better money flying freight, at least for the first few years. There are several operators out there where you can make 40-60K after two years or so.
Ultimately, the goal here would be to skip the regionals. But if you find yourself (in two or three years) unable to do so, at least you'll have the PIC time firmly under your belt, and will be better prepared to become a Captain at said regional than if you had gone to the regional right now and flew in the right seat.
That may sound funny to some, but I do believe that there is nothing that will prepare you better to be a Captain than being a Captain. Airlines hire Captains and one of the best ways, IMHO, to show them that you have "Captain Qualities" is to prove yourself in a 135 environment. Conversely, some believe there is a lot to be said for getting time in a "crew" environment, but unless you're a total @ss, you shouldn't have any problems when the time comes for that.
