For what it's worth, it looks like I paid ~$550 in shipping for my A3-41, delivered April 2020, to Minneapolis MN.
As Festal points out, Felder makes a point of insisting that you do not sign for a delivery if anything looks amiss. It's much easier to sort out damage if you refuse delivery. If you sign for delivery, it releases the shipping company from any liability, and leaves you holding the proverbial bag.
The Silent Power cutter head on the Hammer machines is nice, my understanding is that the same head goes into the Felder machines as well. Chips are nice and small, cutter noise is minimal, no louder than running my saw. That being said, I'd like to eventually bump up to the AD941, in which case there's a TERSA cutter head available which I'm seriously considering. Within the realm of sub-$10k machines, I don't think you could hope for much better than the Felder spiral cutter head.
Something you get with the Hammer (and Felder/Profil) machines that may be lacking in some of the other combo machines is support. While YMMV, I've experienced great support from the Felder technical service people, and there's an active Felder/Hammer/Profil forum with a wealth of knowledge about dialing-in the machines.
Something the Hammer machines offer that I do not think is an option on the Jet or Grizly machines is a mechanical DRO on the hand wheel. I have mine set up for MM, and I can get repeatability to within 0.1mm.
