That's basically how I buy my kits unless I just need one of a kind. Like JT said, bushings and bits are an added bonus and I store my extra bushings in a separate box so I always have back ups. And usually the kits have one or more of each plating which is always nice. If you go to the PSI site and under "Specials" they have a bunch of kits on sale, with potential free shipping if you hit $49.00
