I've also been looking at numerous warranties, though that 1sourceautowarranty place also has a few complaints, here are some links I found:

http://www.usenetcars.com/archive/in.../t-191012.html

they are also currently *NOT* a member of the BBB (just checked today).

I've been checking out autowarrantybroker.com

$1,705 for 36 months via their web site, not sure if I really need an aftermarket warranty yet
