I replaced mine with a Seaward Princess and that was in 1993. I am a liveaboard and cook daily on it and couldn't be happier with it. The customer service at Seaward is excellent too. One last thing, one of the owners owned a GB 36 for many years before he got out of boating and he is very familiar with GB galleys.
I won't say anything about the Force 10 but I have always been told the Princess is a better unit. Since I have never owned a Force 10 I can't say from experience.
