I want to buy a new stage LED light for a small scale wedding party but the price in our country is too expensive. so what

should i do as my budget is USD $500 . I'm buying from online shops. I had already searched on Ebay,Aliexpres and alibaba. Can they be trusted it or not? Is there anything I can buy, If you have a better

option for around the same price range please let me know. thanks guys!
