Those are very different jackets. The mountain hardware is a coat, and too warm for the stated temps. The Nuptse is a jacket, not a coat, and maybe more in line with your temp, but its way way over priced for what you get. Montebell has nice light jackts that would fit your needs, but two things - if you get a jacket with a water tight shell it will cost a lot, but then carryng a separate shell can also cost a lot and it adds to the weight. Hood - I wouldn't buy a down jacket without an insulated hood.

So if you have a suitable shell, there are many jackets in the $150 american range that would suit you.
