Yep, Fruit is one of the best free engines. I prefer Toga, though. Most versions of Toga are rated slightly higher than Fruit. (My biggest problem with Toga, though, is that there are now so many versions that I can't keep track of them.) Actually, much of Toga's design is based on the Fruit code.
The first time I went to install Fruit, there was something that I didn't like about the installation, so I just never installed it. (Although I can't even remember what it was about Fruit that I didn't like.) Maybe I'll try installing it again.
Concerning Pro Deo, I found that you can indeed edit the existing personalities or even create new ones. I'm currently testing some personalities that I made to lower the strength closer to my patzer rating. (All of the standard Pro Deo personalities are either way over my head or way too weak.)
Here's some links in case you don't already know about them:

Edit - I think I remember what I didn't like about Fruit - no tablebase support. Most versions of Toga support either Nalimov tablebases or Scorpio bitbases. Ah, I might install Fruit anyway.
