Looks like a prop from stargate universe.
It's bigger cousin the 319 is supposedly better. I've seen those go for $125 used on craigslist. Supposedly similar in traits to an MD421. So drums, brasses, and other things might work well with it. There's a 319 mod out there, not sure if it's the same for 219 though. Not sure what it does either. I've never had one of those myself. I almost had a 319, but the guy selling it ended up being 40 miles on the far side of town. Which didn't work for me since I too live 40 miles outside of town, on the other side of town.
