The Hadron is certainly a worthy competitor for that weight class when it goes on sale for <$100.
As for the Uniqlo piece -- we'll see how its lifetime works out. I picked mine up lightly used, and have been wearing it 2-3 times a week for short urban errands and things, over the last 1-2 months. So far it still appears in like-new condition. But I haven't taken it backpacking yet, of course. That being said, I think your comment re: ultralighters taking better care of stuff should apply here. That, and I only manage to do 2-3 backpack trips a year, so this thing could easily last for years.
And, as an entry level option, as you said, it would be great. For any of these people, as it were:
"... college students, high school students, scouts, broke chumps, vagabonds, parents of triplets, and those exploring becoming a UL hiker, the initial cost of gear can be downright daunting."
