There's also the Mossimo "Katelyn" available in tan, brown or black for $34.99 - the low heel and perforated detailing makes these a great wear-with-everything summer boot:

These are similar to the Target options, but a little less western. Plus 100% suede: http://piperlime.gap.com/browse/product.do?cid=92625&vid=1&pid=922045002
