What USB wirless adapter

1st, i have done lots of googling and have not come up with a awful lot (mostly snippets of forum posts ect)

I am in the market for a USb wifi adapter, i have narrowed it down to 2 adapters , i think they both support linux but cant be 100% sure:

They are,

TP-Link TL-WN322G

Billion XWL-11GUZX (aka 3011G) (re badged Xmicro XWL-11GUZX i think)
http://www.x-micro.com/main-product-54usbadapter.html

will be using with ubuntu, fedora core and maybe gentoo


What should i get?


Cheers
