Greater Noida's 'all-inclusive' prices are a myth.

Honestly, I'm finding the builder comparison process for my own home much tougher than for clients. I'm eyeing Godrej, ATS, Gaursons in Noida Extension, Sector 150. Brochure mein sab acha dikhta hai, but I'm worried about hidden charges at possession. After paying for a 3BHK around ₹1.5 Cr, will they suddenly spring up extra PLC or EDC? Also, construction quality ka kya scene hai? Plaster cracks, seepage issues – are they real for these big names? Any actual owner experiences, especially post-possession?
