First property search: broker ke claims kitne sach?

Budget finalised, loan pre-approved — now stuck on which sector. Been eyeing Sector 150 for a 2BHK, particularly Aashi Construction Infra ke projects. Honestly, brokers are constantly calling, claiming they can get me a better deal than direct from the builder. Bolte hain unke paas special inventory aur discounts hain. But my parents keep saying brokers apni commission add karte hain, aur eventually humein hi pay karna padta hai. Is it really true? Should I try negotiating directly with Aashi Construction sales team, ya broker ke through jaana sahi hai? First-time buyer hoon, ab samajh nahi aa raha kaha se start karoon. Koi experience share karo, especially about spot discounts and transparency. Kya broker hidden charges bhi bata dete hain ya builder se hi pata chalta hai?
