When it was my money, I bought a Solus Pro having 8.2 software good for '80 1/2--2007. With numerous accessories--cables, battery and charger, OBD1 connectors, OBD2 connector and personality keys, operator's manuals on DVD, etc. $350 shipped to my door. Pricing may be different now.
I've used it for engine, transmission, instrument cluster, ABS issues. Haven't needed traction control features yet.
