Suggestions for latest ESP8266 WiFi module
No, I'm afraid we can't, since we're not ESP8266 salesmen.

However, I would seriously recommend not using an Arduino to communicate with the ESP8266 but instead to program the ESP8266 directly so you don't have any communication worries.  If you want to add an Arduino into the mix at a later date for its enhanced IO capabilities, then feel free to do so - where you can then implement your own serial protocol at whatever baud rate you like (or other protocol even - SPI? I2C?).

All you need is: 


The Arduino core for the ESP8266: https://github.com/esp8266/Arduino
Some form of USB serial adapter (eg FT232 breakout board).


The controller chip on the ESP8266 is considerably more powerful than the Arduino's chip, and the fact that many people insist on using the ESP8266 as a slave device to the lower powered Arduino always seems completely backward to me.

If you want an easier board to program that messing with breakout boards you can do a lot worse than investing in a NodeMCU board. Make sure you go for the version 1 not the version 0.9 since the version 1 has a slightly more enhanced chip on it with more IO facilities than the version 0.9.
