Help! What wireless card to get?!

[tinymouse2]

So I'm getting a new wireless card! YAY! But I have no idea which one to get...
I'm in the UK and my budget is 25 squids. I've seen http://www.ebuyer.com/product/103208 and that looks alright but is there anything better I can get for the price I'm willing to pay?

Our router is the Linksys WRT54GL.

So! Is there a better card I can get than the D-Link one that's in my budget?

Thanks in advanced.

Sorry should just say
Can't be USB but I think you can put a PCI-E card into a PCI-E 16x? (My 1x is blocked by my GPU)

But yeh, PCI or PCI-E (if you can fit a x1 into an x16 lane)
Also I'm hoping for N as long as it supports G (I sometimes use N at uni). I've realised that actually I should ignore budget to an extent. I'm raising the bar from 25 to 40 quid.

So yeh, Windows 7 and 64 bit as well I should point out incase that screws up avaliability of drivers.
