Support for a 'cheap' JTAG board would be a big plus (GuruPlug is only US$40, whereas a BDI3000 is US$2,500 from what I can tell)
You can also look at the Bus Pirate (~$35US) [1], the Flyswatter (~$50US) [2], and the Flyswatter 2 (~$90US) [3].
The Bus Pirate is *a*lot* more than a jtag.
So why would you pay $2,500 for a BDI? Is it simply because the BDI is a single tool that can connect to a wider range of devices (PowerPC, MIPS, XScale) and has Ethernet connectivity)
another plus is that BDI speaks gdb. For ARM openocd plus a jtag dongle (cheap FTDI based) is a really good solution, unfortunately other arches are not so well supported. But I had problematic cases where openocd did not work correctly in the past (especially working with armv7 somewhere between 0.4 and 0.5). I think these cases are sorted out but you may get other problems. Openocd however is open source, so you just can fix it ;)
