it's a great unit. yes, this is super expensive, but is super quiet, has more than enough power, works without a twitch, all the time. What surprised me the most was the noise, there's like none! no buzz, no whine, nothing! Once you get one, you wont go back.
this is an awesome unit.

8/10 for the price,
