Vehicle spy is cheaper than can analyser. Both does the same thing. Can analyser you have to use their dedicated hardware which cost quite a bit. We have four PCMCIA cards from vector but that is obsolete as most PCs don't have PCMCIA slots now. That cost over a grand for each card.
Vehicle spy is cheaper than can analyzer. Both does the same thing and both are license based . I agree with you , but for vehiclespy dedicated valueCAN device or neoVI FIRE, neoVI Blue, neoVI RED, neoVI PRO are required and for CANalyzer , CANCaseXL(which supports CANalyzer) is required .
