Disagree. I have a nice original 20" taito table, and maybe check out the Hankins too.  Generally the Hankins are more expensive, however the 20" Taitos are rare, but they are out there.

Its a very clean machine, have a stab, and you might snag yourself a nice table. Just remember though, the ergonomics are shocking.!

Your right with the ergonomics fast forward  30 years and another 50kg or 60kg and 2 feet in height and then playing a table looks "wrong" especially with a mate the other side
