I used to own a vaccuum table from SOTA. IME, the SOTA vaccuum system imparts a very particular quality vis a vis any other TT I've heard. (These include non-vaccuum SOTAs, and many others - but not any vaccuum systems from any company other than SOTA). Many people love it, others (me included) not so much. This is not a pick or a pan. I'm merely advising that vaccuum hold down is one feature on a TT that -IMHO- must be auditioned before purchase.
