Programming Interface for TI DSP

I'm about to design a PCB for a project with a TI DSP
TMS320C6720(http://www.kynix.com/uploadfiles/pdf9675/TMS320C67...).
What is the best method to use as an interface for getting the program
onto the DSP? I haven't done this part myself before. I'll be using CCS
v4 and my motherboard has usb 2.0 pots and a parallel port but I'd
rather use the USB so that I could keep using whatever cable I need to
get in the future. I'd prefer a low cost solution, I saw some JTAG
emulators that cost 100's which is more expensive than I thought would
be necessary, however it would be helpful to be able to debug when I'm
programming. Thanks
