Trimming Machine need some help

Ok so its almost that time for harvest and its gonna be a pretty large crop. You can see my grow below in my sig below. I am looking at a couple trimming machines .Does any one have any experiance with these trimmers? What is the good and the bad? Here is a video of the one I am looking at..http://www.youtube.com/watch?v=DY_P8kW99lU

I use a Tumbleweed/Samurai. I am also getting a Twister for this fall. I have paid for it and am awaiting delivery. I can trim 20-30 lbs in a day with four people big leafing for me. They work great. If you have a big harvest they are totally worth it. This is the guy I bought both of them from.
