This is my experience with SOTA to date.
I bought a Sota vacuum table around 1989. After about 500 hours of use, the table rather suddenly started having the RPM drop by about 10% to 20% about 15 minutes after starting playing a record, and the speed would be unsteady from there. If I turned it off and waited, it would be OK again - until after I played it, then after a bit it would suddenly go bad again. I contacted SOTA, they said send the electronics to them. They returned that to me, said they had fixed the problem, and charged me $200. Within a month or two it started doing exactly the same thing again. All that money for that turntable, and I can hardly express what I thought about it at that point. I never played a record again for 30 years for various reasons, but beginning with not having a working turntable or money to buy a different one.
I recently bought another turntable, a Michell Audio Orbe SE. Definitely not a SOTA.
I have accumulated a lot of mono recordings over the last few months and have decided to look into getting the SOTA fixed up, buy another arm (I'm using the original I had on the orbe SE), and put a mono cartridge on it. I am going to see what kind of guarantee they can offer that it will not go bad again, and if they ever identified exactly what aspect of their engineered design was failing so miserably. I will see what they say. They have a long ways to go to make me feel good about their product and service again. With the advent of 30 years, I am willing to give them a chance to try. Things change a lot in 30 years.
