Hi!
Few things i like to clear here and these are that i am interested to buy MCU through mail, as i live in 3rd world country and not every MCU is available in market.
Also many of you guys said "it depands on quantity", well lets the quantity be from 2 to 25.
Also Rob Klein said that "It's no use buying the Cheapest MCU if it does not meet your technical requirements!". Well let suppose i like to use them for very simplest tasks like smart display controller or remote controller or some thing very small and easy. But i am interested in MCU which can build system with minimum or no external hardware.
Thanks!
