Welcome to the forum. You'll get better answers if this were posted outside the FAQ part of the forum, which is the wrong spot for this post.
In your area, no, I don't think you'll quite be able to swing either of those pianos, new with a warranty, for $5.5k to 6k. The Hailun is the lower priced piano in the first place, so you'd get closer with it.
Also, keep in mind the dealer experience/prep can vary a lot. From bad to good, some stores I've seen in this part of the country: didn't remove all the packing materials from the piano and obviously hadn't serviced it since uncrating, leave the pianos completely open to the elements or in windows that get direct sunlight, tune the pianos only when they have an interested customer, tune the pianos occasionally and fix only what's glaringly wrong, tune their floor inventory regularly and make minor adjustments when needed or requested. (I'm talking about how moderately priced vertical pianos tend to be treated)
In all those scenarios except the last one or two, you'll end up paying more in the long run, as the piano will need more servicing before it stabilizes. Even when considering a recently made used piano, it's important to get the service history (figure out who was the regular servicing technician, and call them to ask about the piano), because some folks unload relatively new pianos because they fall into disuse, which often means "never serviced". I tuned a 10-15 year old Yamaha U1 in a store. It looked relatively unused, but it was 50 cents flat, obviously not tuned in a decade...the store wasn't particularly pleased when I billed them for 3 tunings to get it back to pitch, but it sold quickly after that.
