Get on SierraTradingPost, Campmor, Altrec, Backcountry, or REI and look for sales. Lots of brands and pricing is far more competitive. Terramar is on Sierra frequently at good prices. Sierra also has a brand they sell called Wickers. We've bought it for the kids and it's pretty good. REI's house brand is good too.
I'm not a UA fan. I've been wearing lots of other brands that did this long before UA existed. Patagonia blazed this trail forever ago (and yes, it is pricey, but works and lasts). I'm sure UA works, but plenty of others do too. UA didn't invent the stuff, they just market it well.
