Extended Warranty purchase

I have 47,000 miles on my 2002 and it has a CPO warranty until March 22, 2008 or 100,000 miles.

My question is, does anyone have any info on after market extended warranties???????? I see them recommended here all the time, but no info on which ones to purchase or that work well.
I vowed never to buy one agian after the headaches I had with the one purchased for my Suburbanouich , long story!!!

Anyway, once agian I know someone will have some good input:typing: :flag: .

Thanks!!!!
