New flat - Best deal landline & broadband?

ItchieFeet

Tried Vodafone dongle as have Vodafone mobile, but super slow.

Cant try 3 dongle as have to return in 3 days and I cant get to a 3 store during work week. Plus price similar to landline broadband.

Have looked at:-
BT line + BT broadband (18mth)
BT line + O2 broadband (18mth + 12mth)
Talk Talk line & broadband bundle (24mth)

Have worked out cost per month over contract length, inc connection & Quidco discount: Talk Talk is best price – but is it the best deal?

Heard rumour that BT are going to drop their prices in the autumn – but need to make this decision ASAP to get free connection!

Tempted with BT + O2 as shortest contract and best reviews…plus only £2 more per month (if sums are correct)!!

Any advice gratefully received
