Nothing wrong with SF kit's price. For $5k you get real customer service and some one with knowledge willing to help you even if you do not own their product.
If someone else wants to produce a kit, great. I'll wait to see finished products and real results before final judgement. I did however notice, in the description of stage II it states ceramic coating, SF uses SS, thats more money right there. Sure you can build a cheaper kit, but look at everything apples to apples before you speak.
