Xtra is the leading ISP over in New Zealand and for the past... I don't know how long... it has been the worst, by far.
Our current plan at $50 NZD per month ($33.50 USD) is for the max possible download speed over here (3.5mbps), 128kbps upload, and 5GB of bandwidth. It doesn't take a genius to figure out that this plan is crap, as most other ISPs provide the same specs for a fair amount less.
Recently, Xtra changed all its plans to max download speed, to rival another ISP (which was still doing better), but it looks like they took the hint and went a step further.
The $50 plan, and only that plan, now has unlimited bandwidth instead of 5GB. Basically, this makes it the best plan on offer if you don't care about upload speed, because no other commonly known ISP in New Zealand offers a plan with unlimited bandwidth.
There was some tweaking of a few other plans, but they all still suck.

The only real catch on it, which is easy to avoid:
