Just wanted to know is the Grid 7720/7730 proving to be reliable? are racers having any common problems with them? I would like to get the latest/greatest with the ability to have the add-on options later. the main reason for asking is that I've had a 7al2 for 10 years without a single glitch, I have not used any of the digital boxes yet.

We integrate it with the racepak and mainly use it for timing curves "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

I have one but haven't used it, sort of intimidated by it right now. Thanks I use it for all the basic ignition stuff...rev limiters, launch and nitrous retards. Once nice thing is the ability to have files saved that you can quickly download for different conditions. Comes in handy for those "unsanctioned" races where there's zero prep.
