Krishna Kunj property: prices aur builder quality?

Okay I'll be honest — Krishna Kunj mein property dekhna thoda confusing ho gaya hai. I'm looking for a 2BHK, my budget is around ₹60-70L. Builders like Balaji Group and Madhav Group ke projects dikh rahe hain. Par honestly, prices seem a bit high for the amenities. Kya yahan ke property prices justified hain? Aur in builders ka actual track record kaisa hai in terms of quality and timely possession? Koi hidden costs bhi hote hain kya? Thoda real advice chahiye.
