S-Bus to VME-Bus adaptor experience ?

[Udo Hollaender]

We are currently using a VME-bus machine (SUN 3/470) with additional VME
cards (bought and self-developed) for our application.  Right now we`re
considering choosing a S-bus SUN SPARC 2.

* Does anyone have any experiences with VME to S-bus adaptor?
  (Performance)
* Any particular brand names to seek/avoid? 
* Any special advice (e.g. sound reasonable/ no mixed architecture)?
