This may not help all of you, but if you can purchase the PlayStation 4 with a credit card you can very likely get an extended warranty through your credit card provider for free. MasterCard, Visa, Discover, and American Express all have varying degrees of coverage. Different banks and specific promotional cards may offer protection above-and-beyond what Visa, et. al. provide.
This could get you covered for at least two years and 90 days.
Sounds like your luck has been less than stellar I hope things turn around for ya. I hear you on the disposable income - I have a toddler and a teen, and it ain't easy. Especially come holiday season with 8 billion friends and family. :|
