What is a cheap STR710 debugging solution?

[XFD]

I'd like to gain some experience with a real embedded chip and selected the STR710 chip. Now there are quite a few kit offerings available, but they're all broken in some way (code limited usually).

So from my digging around, I found GNUDE for ARM. This by itself is a big step as I'm not spending $3,000 for some software package. Now, to really make the little board I'm building up useful, I understand that I need to have a debug setup. My searching has come up with near nothing that is low cost and useful. So I would like to ask you guys for some suggestions on a cheap/free (I can build it from a schematic if needed) JTAG debugging solution.
