I did find an online LaTeX equation editor that makes svg files.

In a quick test I found that the resulting SVG file did look very nice in an epub (Thanks for the tip!!!) Only problem I had was the editor I found was IMHO not very user friendly - steep learning curve (old dog, new tricks)
Do you have any other techniques or maybe a 'friendlier editor' ??
