Plusnets Broadband Home Lite must be one of the cheapest 512k adsl services around at the moment at £14.99 (inclusive of vat) but with a 1gb restriction a month from July 1st.. i'm not so sure it will be suitable for everyone.
Plusnet's website details/gives an example what you can download/leech for your 1gb a month...
but wait...
if you look further down Plusnets web page it says you can bbb buy (i hate swearing)
extra gb's at £2.50 upto a max of £10 extra per month...
I hope other Adsl isp's dont follow in Plusnets footsteps to restrict adsl packages.. because if it becomes the norm then adsl wont be a cheaper option to cable BB
