What are you looking to do with it. It’s a fantastic tool if you do a LOT of diagnostic work. I’ve considered a Modis in the past, solely because it “mostly” has a Vantage built in.
I have another brand of scan tool now, but will likely use a Vantage/Vantage Pro as a stand-alone scope sometime in the near future
the modis has the vantage pro built in, but with similar software the interface is identical. the component tester pretty much handfeeds everything to you, but its expandable once you get into current ramping and secondary ignition. if u get any questions about it let me know, i know the tool inside and out
