There is the N2PK VNA thats avaible as an board + digikey partlist and gives a 120dB dynamic range VNA from 10KHz to 50MHz, or there are the VNWA avaible ready buildt from the UK with 70-80dB dynamic range to 1.3GHz. Those are the ones I know that have true phase reading and can solve for the sign of the phase. Of course there are older HP or R&S boxes, and probably others as well, and by shopping around one can get decent gear at a fair price, but with some added complexity of doing the measurments. Having an VNA helps doing measurments, but a lot of cool things can be done with a spectrum analyzer, adding a simple return loss bridge makes that into an quite decent scalar VNA. Brr.
