I trained with a little over 500 ham and 1500 spam, so far nothing has been
misclassified and only a few unsures in just over a week of use.  It even
captured a bunch of double-bounced spam to mailer-daemon on my server (it 
gets delivered to my inbox).   A 1:3 ratio does not seem to skew things, 
at least not for my typical mail.
