lewm,
The early Sotas, the ones with the black top plate, metal control cover plate and wood sides, sometimes had an issue with pitch stability. I have owned a couple of those. However, the Sotas from Series III on do not have that issue. Series III tables have wood tops and control cover to match the rest of the table. Sota has had 30 years to develop and refine their product, whose basic theory of operation has not changed. Tweaking an already good product for that period of time usually results in a great product.
