This will be one of those 'it's the journey, not the destination' scenarios. It's such a personal thing, and you need relatively little equipment to be a competent butcher. I regard myself as being of a high standard when it comes to deer processing, and it's taken many years of purchasing 'fad' items, to finally settle on a good boning knife that suits you, a steak knife and a saw.
My personal preference are knives that are easy to keep an edge on, so they tend to be relatively inexpensive, and a saw of fairly good quality, and all of these items go into the dish washer, on a high heat. I use Victorinox knives, and they really do take some beating, in my personal opinion.
Focus on the butchering techniques, not the fancy equipment.
