My favourite scan tool is the Ford IDS.... a touch spendy for the hobbyist
or DIYer....

I'm not familiar with the Actron tool but I have heard many that enjoy
AutoEnginuity... I will add that you need to check closely to find the price
for what you want out of the tool. I understand that there are different
"levels" and such.

Of course the ability to run the KOEO and KOER on demand tests is important.
Accessing the data stream goes a long way to making life easier. Output
state control (the ability to make the module command an actuator for test
purposes) is also a desireable feature though I'm unsure if either tool will
give you this.

Finally.... the ability to communicate with proprietary modules (ABS,
instrument cluster, GEM, et al) is going to be important. None of these
modules can be accessed without using a capable scan tool. And don't forget
to make sure it can communicate on CAN networks...
