Need your opinion on wireless setup

Hello everyone,
I want to set up a wireless network and before buying any hardware i wanted to ask for your opinion.I want to buy a router and 2 wireless adapters. So far i have thought of 3 possible configurations

1) Linksys WRT300N router + 2 WUSB300N adapters
2) Netgear WNR384M router + 2 WN121T adapters
3) Netgear WPNT384N router + 2 WPNT121 adapters

I want to use the network to transfer files between 2 pcs and share my internet connection. I am not interested in range,however i will transfer large files so i want the fastest possible setup.
The walls of my house are made from bricks,cement and iron so this will affect the wireless performance a lot. However i am only interested in ranges up to 30m.

Which one of the 3 setups would you pick up?

Thanks for your time in advance
