Seems Slingshot have introduced some pretty amazing data plans...
$70 for 250 gigs.. and half price for the first 6 months.. $35 for 250 gigs...
or for lighter users.... 50 gigs for 25 dollars..

I am currently with orcon but its seriously tempting to move over. 

Seems telecom have made moves on their pricing recently too, now slingshot...

Any chance we are going to see anything from Orcon? throw us a bone please!
