Yeah ebay, craigslist etc. As far as the law goes 88turbo is right you're not supposed to purchase it without license, seeing as it was phased out of use, banned effectively in vehicles. But the stuff is honestly all over the place, especially ebay. Prices will vary but it's by no means out of reach to get enough to charge your average vehicle. No way for any authority to truly prevent it being sold secondhand.
