I really think you should do some more research before dropping a lot of money that other people have donated to you. You realise bulbs are like £5! Hardly a deal breaker! I can agree that H&S can be an issue but if you want to work in films then you are going to have to learn how to use the equipment someday. Do your parents let you use the oven? I would say it's just as dangerous, it's just that every time you use it you make sure you take precautions to ensure you don't burn yourself or set anything on fire. It's exactly the same for a lighting kit. If you look after it and have some common sense then you won't make any mistakes! To put it into perspective one of those red heads from the craigslist guy is 5 times as powerful as the whole LED kit. Don't forget that if ever you put anything in front of the light (gels, diff, ND) then you are reducing the amount of light it produces making the red heads much more flexible as it's always easy to reduce the output but not so easy to add to it.
