There are a few stock parts that I don't particularly care for. Probably the first thing I would recommend swapping out is the board. Virtue OLEDs look really nice. But I've never actually used one. They are expensive. You can get a Virtue Redefined board for around $60 from Virtue. That is a steal. I have a pre-Redefined Virtue board in my DM. Which was $130+ dollars new in 2006. The OLED boards drove the prices of the LED boards way down over time.
I'd also recommend a few more backs or kit, a magnetic trigger return or at least a lighter spring, a different ASA if you don't like the stock one & a feedneck similar to the DM7-9. I'm crazy about those feednecks.
