I only have experience with the Digital-6. I bought one when they were first released, paid over $350 for it and it failed after 1 season of little use. Just out of warranty, I asked MSD if they could recondition it (even at some cost to me), but they said they were not serviceable like the old boxes because they are fully potted inside (so much for improvement). Later I find out they were potting them the first few years to protect their technology from being reverse-engineered. That left a bad taste in my mouth, not helped by multiple Blaster SS coil failures on top of it. On the flip-side, I have had ZERO issues with my 17yr old 6-BTM box. All that to say, I dont know what to recommend to someone these days...
