You had asked about the Dallas office, so I will comment.
I recently bought the A3-31 from Sam Striegler and had a good experience.
I saw the machine at their showroom (I happened to be near Dallas one day for business). I had unexpectedly arrived after hours, and it was actually his suite mate who kindly let me in and ran that and a few other machines for me. He has a furniture shop and is an end user rather than a salesperson, but he was very enthusiastic about their equipment. I needed a jointer and not a planer, but I liked the combo.
I called Sam and told him what I was looking for, and he answered the questions I had. He was prompt at returning calls, and he actually answered one of my calls to his cell phone when he was traveling in Austria. He said he would send me a quote to review, and I was interested to sign and send it back with the 20% deposit. They had several in stock and said they could deliver whenever I was ready.
I had some technical questions, mainly about electrical requirements, and he put me in touch with Brian Lester (out of Delaware, I think), and he answered those questions promptly. (Some of the written documentation calls for 30A, which I had, but some other documentation and the actual tag on the machine said to use a 20A circuit, so I had an electrician make a subpanel that they attached to the back of the A3 with magnets. Photo will be posted below).
This was my first time to buy equipment that I couldn't put in my SUV, and I was worried about getting it across a gravel driveway into the garage and unloading it. They arranged shipping and told me what to expect in terms of the driver and the size of his truck. He called me 30 minutes before delivery. It arrived in good shape. He placed it in the garage for me, no problem.
A few days after delivery, Sam called back to make sure everything was A-OK, which it was. Pretty much every aspect of the deal was easier than I had expected, and even the electrical issues were, in retrospect, fairly straightforward.
It was very different from, and candidly, more difficult than, the usual retail experience at Woodcraft or Rockler, but my guess is they are more geared to dealing with professional shops than hobbiests and they didn't have a showroom in Houston. If Sam had sent me a quote without letting me know it was coming, it might have rubbed me the wrong way with all the legalese, but I was expecting what I got.
It is a shame that you had a bad experience with their responsiveness. Had that been my experience, I might have gone a different route, but I am really happy with the machine.
Here is the subpanel I had installed.
