Noida investment: Unitech vs. other builders?

Hey guys, I'm thinking of investing in Noida. What's your take on the current market conditions? Is it a good time to buy, or should I wait? I'm looking at properties in Sector 39. Has anyone invested in Unitech Group projects recently? Mujhe advice chahiye about their current projects. What's the expected appreciation in that area? I'm a bit worried about construction delays. Kya aap logon ko pata hai about Unitech's current status? Which one is better for investment – under-construction or ready-to-move? What do you think? Any suggestions would be helpful! Thanks!
