Generally, i'm a budget backpacker (except for some long term survival gear which is quite expensive, like a collapsible titanium wood stove but that's, i guess, a different category and for a different forum). But i find if you're willing to do the extra research, thinking, and/or shopping around, you can often find good deals. Then there is MYOG, a whole nother subject and one i'm still a newbie in, but so far really enjoy despite my limited skill set/experience.
The other day i was at Marshalls and was surprised to find a super light windshirt made by Nike that was going for 7 dollars in the clearance section. I weighed it at home, only 2.4 oz. Has some definite issues, like it doesn't have a hood, and doesn't seem all that durable and only has a partial zip, but hey for 7 dollars i'm sure i can manage and/or modify.
I will admit to sometimes wishing i could afford Cuber Fiber most everything, Titanium everything, Carbon fiber, etc, etc type stuff that is often so lauded here, but those are only during my rarish weak moments. Even things like Patagonia's Houdini is generally out of my price range and hard to justify (again, unless it's something for possible collapse/long term wilderness survival use).
Another example of cheap, though i suppose it's more a MYOG thing, i bought some bamboo poles to make into hiking poles. When i cut them down, i guesstimate they might weigh somewhere in between 9 to 12 oz for the pair, which is significantly lighter than a lot of aluminum poles, and similar to some carbon fiber ones.
Got my pack on clearance, a GoLite Jam, and while not SUL it's decently UL i would say.
