If you don't want to spend a lot of time managing your own local rules, I'd recommend scoring in a second statistical filter, one that supports multi-word tokenization. These can do better than Bayes with type of spam you mentioned because they can match patterns made out of words that are themselves neutral. I say patterns because once you get beyond 2-words the tokens can include gaps. I use Bogofilter configured for 4-word tokenization and DSpam with orthogonal sparse bigram tokenization, but I've scored down DSpam because it was contributing to most of my FPs. I recommend trying Bogofilter. No need for a plugin, just pipe your mail through it and score the x-Bogosity header.
