I need Guitar Gear Cheap!?!?

I Need a half stack marshall that is great for death metal, and im looking into buying a jackson dk or a ibanez xiphos series. I am only 16 and i make very little money. i need a way to get that type of gear, without going into debt. im sick of seeing people who blow at guitar, that have this gear because mommy and daddy are doctors and will buy whatever their heart desires. Please help me out! Oh and Im going for a Necrophagist sound. if that helps on what amp I should get.
