One thing must be said, Delhi guys suck, they just don't post experiences..
I have 1/22 and guess you have 1/27. All these docs should be the same, my guess for lot of people talking about Dr. Jain is cause he is in South Extn. where a lot of $s can be coverted to Rs..
Seriously, I plan to take 2 appointments with 2 doctors on consecutive days just in case..
If you want we can talk while in Delhi and I can update you of our experience.
Let me know and I can send you my contact no. in Delhi.
