Splitting it will get you most money but you have to live with the knowledge of that you've butchered your lovley Amiga just for profits. To me, Amiga have never been about earning the most $ for the things you don't need. It's been about the fun and the friendship and helping eachother out. I've yet to splitt anything for profits, I rather see a hole working unit go that I know will find a loving home and knowing the new owner, who's possibly a new Amigan, won't have to start months of search to find things that I could've splitted from it if I wanted to squeze out the last $.
