I just received my A3-41 a week ago and I finally have it unloaded, unpacked, and in my shop. There were no dips in the bed or manufacturing issues thus far. I will be powering up the beast today and testing it out.
If they have them in stock in the US, I would not hesitate. The extensions are on backorder for another 6-8 weeks along with the 140mm to 4inch dust port reducer.
