Can you accept not getting the thing you want for a close facsimile? That is the question

I've been a little fixated on my friend Emily's post from a few weeks ago about striped boatneck tops. In fact, I've probably clicked on it 96 times, gone to the website, almost bought the shirt, and then thought, "Wait, is $160 too expensive for what's basically a long-sleeved tee? But I want it! And it's eco! Yet it's still basically only a long-sleeved tee!" And on and on in my own little trying-to-be-responsible lameness. Since this tragedy started, I have seen some very cute, very similar pieces on eBay that are about an eighth of the price, for about 80 percent of the goodness. Should I acquiesce and purchase the original? Or do the right thing and pick up this, this, or this (or all three) and feel satisfied in my frugality and not-fulfilling-each-and-every-one-of-my-desires adultness?
