Don't try to buy molds or injectors from overseas. Buy from USA companies only. If you're going to buy an injector, buy a basstackle.com injector. Which brings up another topic, don't go cheap on your molds and injectors. They're like tools, buy a quality one the first time and you won't have to buy it again in the future. You don't want to buy a mold and have to modify it yourself. If you buy a mold and it doesn't shoot right, ask for a refund or replacement. Trying to modify molds yourself will probably lead to frustration (unless you have a lot of experience) and then you'll probably quit the hobby. Companies like Bait Plastics and Basstackle.com have been good to me.
