I've just discovered that UFB is available at my address and have been comparing offeringsSlingshot seem very cheap (all prices unlimited data and including home phoneline): - slingshot 30/10 - $89 - Spark 30/10 - $109 - Vodafone 30/10 - $105 (increasing in Feb?)Have I missed something here? If not, it looks like a switch to Slingshot is imminent
