hi, to be honest i wouldnt consider kingston if thats how much they charge.
may i suggest you look at bt or even aol. They can supply free modem, free connection. and charge i think its 25quid a month bt and 28quid a month aol.unlimited 512kbps download 256kbps upload.
Im on aol, the latest software. aol 9.0 has NOT caused a single problem on my computer and alot of other people on here and people i know reccomend it.it even worked with my home network.,and i assure u, i dont work for them!
helpline free aswell btw.
but too answer your question, kingston seem to be charging you a liiiitttllleeee too much.
try someone else
