Gurugram builders: hidden charges are a real scam

Okay I'll be honest — I'm stuck choosing a builder for my upgrade. Currently in a 2BHK in Sector 65, I'm eyeing a 3BHK or villa on Golf Course Ext Road ya Dwarka Expressway. Looking at DLF, M3M, Emaar, Godrej. Price jump is massive. Hidden charges worry me. Do M3M ya Emaar hit you with extra costs like PLC or maintenance deposits at possession? What about long-term construction quality? Does Sobha's reputation mean zero seepage or cracks after years? Customer support post-booking? Signature Global aur Godrej are responsive, but ground reality kya hai? Already have a home loan, can't afford surprises. Which builder offers better long-term value for end-use? Gurugram experiences please!
