Hi there,
I don't have any advice, but I do share your feelings. I started an upgrade myself and stopped at the point where the install of the board would have taken place. Not feeling confident enough, I shipped it off to Eutronix and they were able to do it. There were problems though, but Eutronix did there absolute very best at getting my empeg back to life. I'm so very happy to have my empeg working again, even though I only have 16 of 64meg, but that's better than the 12meg :-)
