Greater Noida buyers: Affordable housing options ab kahan hain?

Spent the whole Sunday checking out options in TechZone IV, Noida Extension. Honestly, my budget is tight. Kya affordable housing ab bilkul gayab ho gaya hai Greater Noida mein? Builders jo advertise karte hain, woh final price se kitna alag hota hai with PLC, parking, sab mila ke? Not sure if I'm even looking at the right segment. Any advice?
