These are pretty new markers, so I doubt you'll find anyone with long-term insights.
When I played a couple of weeks ago, there were two Black Draguns on the field. I talked to the owners about what they thought of the markers, and came to some of my own conclusions. I also played around with one inside of a store. Here's what I found:
1. Low price
2. Fast trigger (feels like a mouse click).
3. VERY loud out of the box (first time a paintball marker hurt my ears).
4. Poor accuracy out of the box.
5. Lightweight.
6. Slight kick.
7. Cheap anodizing and polishing.
8. Questionable build quality. The markers I examined had heavy scarring on the bolt after just a little use.
9. Break A LOT of paint out of the box.
Out of the box, the marker runs at high pressure with no regulator and a cheap barrel. Using a quality ported barrel, installing a regulator, and converting to low pressure would go a long way to increasing accuracy, reducing ball breakage, and quieting the marker down.
Personally, I would hold of purchasing this marker until others have had more experience with it. Also, other manufacturers are releasing competing products for similar prices. JT will release new electronic markers very soon, and Kingman and PMI both have electronic markers out. The Piranha Pro TS with Storm frame is a nice marker with lots of upgrades, but costs a bit more.
