for perl ones try a couple searches on your engine of choice and see what's around.

Perlfect works fairly well. The only problem that I have with it is the spidering process.
My host kills any script running over 60 seconds; thus, I can only index a few thousand pages before it times out. Make sure your host is less restrictive, if you plan to use Perlfect.
