I just got to use one of these a couple of weeks ago. A guest artist at our shop had a few (looks like he's actually listed as one of the artists using the machines...)

I only used it for part of one tattoo as it is clipcord and I use rca, and switching around was a hassle.

From what I saw and felt it is a nice, light machine. Build quality was solid, but I was a little surprised that it was a bit louder than I thought it would be.
It packed color easily with a 9mag bugpin, but thats all i got to do with it.

I have actually been looking for them, because the guest artist spoke english/german/hungarian and when he told me the name I had no idea what he said as his accent was so heavy, and I asked him like 5 times.
