Spinner,
Since talking about alternative engines on this forum is such a touchy subject, you are probably better off looking for info in other places on the internet. There are a ton of forums on Yahoo and other non-VAF sites.
There is some good info here, but even mentioning alternative engines usually just attracts people who want to criticize those who would venture beyond the security of a Lyco. In fact, having said that, you are almost guaranteed to see half-a-dozen Lyco-lovers pounce on me within the first hour for offering this observation.
Now, don't get me wrong, I am not suggesting that you ignore any info that you find here. Installing an alternative engine is not for the timid. You very well could get ki1lled. Keep this in mind when looking for which alternative to use. Know your limitations, and figure out your goals.
Cheers,
Tracy.
