First home jitters: Noida Extension builders, kya expectations rakhoon?

Godrej ya ATS ka construction quality sach mein kaisa hai Noida Extension mein? Log kehte hain hidden charges bahut hote hain, especially Gaursons ya Mahagun mein. Mera budget ₹80L ke around hai 2BHK ke liye, Jewar ke paas investment bhi dekh raha tha. Book karne ke baad customer support kaisi rehti hai in builders ki? Koi experience share kar sakta hai?
