I may have to go to Lowes later today, and I'll look at 'em for ya. I don't have a United catalog, so I'm not what size you're looking for. But if any of these will work, they're something like $2.69/pair. Or maybe that was each. Anyway, if they'll work, it beats $17.00 all to pieces.
'Sides, you know how us Southern folk love a Lowes or a Wal Mart....YeeeeeeeHaw!!
Oops! My link didn't work. So here's a picture of a black steel hinge at Lowes: 2 for $2.28
And if you can use the kind on the right, they're in chrome, a pair for $2.17.
Just search for LOWES, click on the first search result, type in 'hinge' at the top right where it says 'keyword', then click on 'cabinet hinges'. If you're looking for something small, they may have just what you need!
