cheers m8,just looked n ebay for 1, loads of options any suggestions on which one to go for?and will any of them work?

Pretty much any of them will work - most will advertise either 54mbps or 108mbps - obviously the 108 is 'meant' to be faster, but with error correction etc. it's a bit of a 'six of one, half dozen of the other' kinda situation...
so as long as it states that it will do 54mbps you should be pretty sorted
