Most starter kits are a mix of one or two decent things and a bunch of stuff you'll replace within six months. W I'd actually buy first are a good swivel knife, a stitching groover, a set of pricking irons (not cheap diamond-shaped ones) and a proper stitching awl. That's your core, add a wing divider and a beveler and you can do almost anything at a beginner level. The hole punch set and the mallet will matter too, don't cheap out on the mallet. Everything else can come as you figure out what you're actually making.
