I have to mirror these comments with the caveat that my connection is a (soon to be killed) Bonded BE connection of 7Mb/1.6Mb and a neighbours house I back onto less that 30m away have the option of 330/30 FTTP.
My main comment on the experience of using this is that you guys must be very frustrated if you have to use a <10Mb service after getting used to >100Mb!
On the cost front, I pay £64/month for my bonded connection plus line rental for two phone lines at £30/month. So by my count £50 + £16/month for 300Mb fibre is the bargain of the century!
P.S. My sig is the best case connection I'm getting back unless I part with over £100/month for a bonded connection plus 2x line rental. The gap between BB haves and have nots is mental!
