I got my own LPC2106 board going with the GNU tools and the Philips flash 
loader utility. I then built my own JTAG interface and used it with the 
Macraigor OCD Commander utility. Then I got the the Rowley tools, which will 
load programs into flash, and works very well with a Wiggler or other 
compatible JTAG interface. The Rowley debugger allows debugging of programs 
in flash, I don't think that the other debuggers do.

So, for a minimum outlay, you need the GNU software and the Philips flash 
loader, and a suitable target board (Olimex's are cheapest). For debugging, 
you need a JTAG interface (make your own or buy one from Olimex). The GNU 
debugger (GDB or Insight) work either via an RS-232 connection or JTAG. The 
Rowley debugger (and the others, presumably) are much easier to use than GDB 
or Insight.
