Can you get Smart Telecom? Broadband is only €40, ie €15 for BB and €25 for LR.
This is for 3Mb Down / 256Kbs up with no contention or download limits.
Compare this with [broken link removed] wireless which is €47.19 for 1Mb/256Kbps. Although they do have a cheaper package for €30 which is 512Kbps/128Kbps. Also, €99 installation.
So although you get a phone line with Smart, it might still work out cheaper.
I think they have a 3 Month free special offer on at the moment.
