I took a much shorter course (ten days) in New Zealand from Alpine Guides at Mt. Cook. I had a great time and learned the basics of rock climbing and alpine mountaineering. The cost was reasonable.

The weather there can be quite good, the temps moderate, the terrain varied (including glacier travel), the people friendly, and great scenery.

Here is the link to their site-

the seasons are reversed, so keep that in mind.
