MSI Neo2-FR has eSata and is pretty cheap for the quality. That's for current gen, no doubt you could get something older for much cheaper but if I take your criteria too literally then just go to your e-tailer of choice, put "esata" in the search box and order the list by price.
You can buy PCI and floppy bay ports that have eSata on one end and an internal SATA connector on the other.
