I would buy a 10" chef knife for around $75-$100, a decent curved blade 6" boning knife and then I would buy an Apex Edgepro. Starting out, a decent chef knife and boning knife can handle pretty much anything. The key is to keep them sharp and the Edgepro will excel at that. Additionally,a bread knife is great for slicing ribs and brisket so pick up a cheap dexter 10" one and you will be good to go.
