i'm currently with virgin in my student digs,i have the XL package 20Mb/s and obviously its not as fast as advertised but overall i am happy when downloading i often get speeds of 1.5MB/s from a good host sometimes up to 2,uploads not that great though i get about 1 Mb/s up (about 75kbs),cant say that i have seen to much throttling going on i just recommend not downloading between 5-10 at night and i think its a pretty good deal overall.
Im pretty sure you can decline the installation charge if you want
for the wireless equipment required im pretty sure they just mean they are not going to send you out more equipment like they do when you first sign up.
also check that its £3 a months every month not the old for the first 3 month trick
hope this helps
