I think N93 as it is a better phone than N73.
My brother bought it a few days back from the gray market for Rs 35,700. IF you think 35,700 is okay then go for it.
Why i think it is better, because
1. From the many reviews i have read, N 93 has the best sound and optics than any other nokia till date.

2.While you still have all the features n73 has you still get TV out (which is superb) and WiFi (which is essential).
While initially i also thought that it would be quite bulky, it feels really good in your hand, it has that industrial feel to it.
Anyways this what i had to say...
