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/TMS320C6720BRFP200.pdf). 
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
