Query: probably the best option out there

I am familiar with a full range of diagnostic tools and techniques. Everything from large flow charts, a multi-meter, bookelets and huge amounts of time to comically oversized built in garage systems. Pound for pound this the best compromise I have seen. Snap on offers some impressive functionality, with even more impressive (massive) prices. The 9150 is neat with all the accessories, except even full time garages would do well to consider if the customer base they serve really will need the full set of connectors. In fact I have seen several area garages that use the 9135.If I were paying list I would to, but, I got my 9145 on Amazon for 209.99 less 25 and they offer free shipping (slow free shipping-but you get what you pay for) The update-ability and upgrade ability along with the ability to read MFG specific codes mean paying the difference from the 9135 is worth while, and IF you ever want an older car adaptor they are available singly.
