Same here.  The ability to burn bootloader code into flash w/o
having to write any code saved me enough time that it paid for
itself right away.

Big plus: the BDI2000 supports GDB natively (it speaks the GDB
"remote" protocol).  All other current products[1] require that
you run some sort of converter-daemon that talks "remote" to
GDB and then talks some proprietary protocol to the JTAG
interface.  Some of those daemons are Windows-only, some will
run on Linux, all are a PITA.

[1] The EPI Jeeni is supported directly by GDB since it speaks
    the ADP protocol which is what is used by the "rdi" target
    module in GDB.  The Jeeni is a fine product, but AFAICT has
    more or less been obsoleted by a newer product (Magik) that
    speaks some proprietary protocol that requires a
    converter-daemon when used with GDB.
