Love my Eastman as well. Bought an E6D a couple of years ago and it's fantastic. Balanced tone, stays in tune, beautiful guitar. It's not a D18, but it didn't cost $3000 either.
I've used Addictive Drums 2 for a long time. I wouldn't say I'm too deep into that ecosystem to switch, but I'm super used to it and it works well for me.
