I've been playing Roland V-Accordions for about 4 years now. I have an FR-7x and an FR-7xb, which were my first two digital accordions. I purchased an FR-8xb Dallape model last year. It took me a long time to get it, because the chromatic accordions (that's what the b stands for) are not as popular in the US as they are in Europe. I also have an FR-3xb, which is not as elaborate as the 7x or the 8x, but the 3xb has the same range as the 7xb and 8xb, but is not as heavy. (Note that the range is only the same on the chromatic model 3x, the PA has a shorter keyboard.)
When I play the 3xb, I usually use it to play accordion sounds only. I don't have any complaints about the sound at all. The only problem I have is that I haven't found the right setting for a bellows shake. I can do one on either of my 8x's though, so maybe one of these days, I'll be able to get the bellows to the point that I want them on the 3x.
Tonally, I find the accordion sounds on all five of these instruments to be excellent.
Bear in mind that I also have several extremely good acoustical accordions, including the Palmer Converter Emperor that belonged to my father. It has excellent reeds and is in perfect condition, even though he left us nearly 20 years ago.
Regarding the production of these instruments, the Fatar company took over production in 2014 and have been producing them ever since. My FR-8x was made at the Fatar facility and is at least as good as my FR-8xb, which was made at the Dallape plant.
I find the FR-8x much easier to program, and I have zero complaints about it.
It took me a couple of weeks to get the bellows setting the way I wanted it. I wanted to be able to bring the sound from complete silence to fff without any difficulty. It took a little experimentation, but now, I've got the sound I want.
Regarding the "local music scenes" here, nobody knows they are digital accordions except by either reading the name on the instrument or when I decide to play a saxophone or organ stop.
