there are also usb ones, which are definitely faster solution (with par. port its around 6 minutes to push 64kb of code)
The parallelport Jtag is much faster.
The bitfiles for my Spartan x3s1000 have a size of 403 KB, it tooks nearly 12 seconds to configure the FPGA via par port.
Cheap Xilinx lpt port jtags are available on ebay.
For developing i would prefer always the jtag solution.
