Well besides the obvious price difference, the Digital contains every thing in one package. Timing control, rev limiters, output ability. I've had both set ups, they both work well, obviously the 7al is easier to install however if you require timing retards or any output controls they would need to be added. Besides the installation wiring you can pretty much have all the features with a 7al but you need to add alot of extra modules. If $ is not an issue I'd recommend the Digital, once it's in you can pretty much do any thing you'de want to with it. Joe
