Given that the Strat is the most ubiquitous guitar on the planet, only associating it with Knopfler, Marvin and Rodgers is to undermine its usage, but each to their own POV. It seems that your requirement is a double cutaway guitar with single coil pickups in the neck and middle positions, plus another s/c or splittable hb in the bridge. Ibanez and Yamaha are good starting points and both have affordable offerings in this format. However, if money were no object, a PRS 513 would cover every base.
