I've had Smart for a few months now
Getting consistent downloads of 1.97Mbits at any time of day or night
Hanging off Beggars Bush Exchange (Ballsbridge, Dublin)
Set up was fine, and when it fell over once, after a few weeks, a quick call to them had me back online in about 40 minutes
There have been a few issue with double direct debits, but the technical side of the service has been fine
I had tried
IBB Ripwave, but the coverage at my house wasn't up to scratch, even though I am well inside their coverage (terraced house amongst many others with equal-height roofs means a signal doesn't get in the windows too well)
I've no connection with Smart, other than being a happy customer, but if you want to know whether to wait for them, I'd say yes...
