Slingshot Price increase

WE have naked VDSL with slingshot and when this months bill arrived it had gone up by $8.95 (now $93.95/month)

I have tried to ring them twice but couldn't spare enough time to get through!!

I had a look around and www.unlimitedinternet.co.nz seem to have the same plan for $69/month

I know its not a huge difference but we are on a tight budget $24.95/month *12 $299.40/year

Does anybody have any pros/Cons on doing this swap??

Thanks

David
