Thorsten Trenz has a spartan-II development board with download cable
included for 99€. I am confident that he will sell you a seperate
download cable on request, albeit it is not listed in his shop.

Please don't. The cable has lots of flaws. Search this newsgroup about
that topic.
Design your own cable. With heavy schmitt triggers added. And sell
that.
You can use a 1$ cpld and use seperate pins for the schmitt-trigger
feedback.
There also is an open source usb downloadcable available somewhere on
the net.
