680X0 accelerator boards on SE: Recommendations?

[nghiem]

Our Mac SE is too slow for our application. We are interested in
installing a 68020 or 68030 accelerator/coprocessor board.

Has anybody has success/frustrations with any of these boards? Has
anybody run AUX on one of these boards? Which version of MacOS is
supported on which boards? Has anybody had problems with a
25 Mhz rocket-board?

Any hints, leads, recommendations, criticisms welcome. I do need  
your comments if you have hands-on exposure to any of these boards.
