It's even worse than "what will this look like in a year?". If it takes 4-6 months from when you pay the money to build a product to when you have that product available to sell to a customer, and you don't know how much your parts are going to cost OR how much you're going to have to pay to the federal government when those products finally clear customs (or what legal hoops you're going to need to jump through to get that product clear), how can you operate?
