i have the solus and the vantage pro.the solus is very user friendly and comes with a training dvd and access to the training website that snappy has.it is a very powerful tool and is great forbi-directional testing and also graphs.i got mine with the 10.2 and then purchased euro and asian.how ofteen you update is really dependent on what you work on.me,i'm an indy shop and most of my work is done on cars between 4-8 years old so i don;t need to update very often at all.and you are able to do a lot of functions on newer cars under the global platform, i would highly recomend it.
