I recommend Olimex ARMJTAG.

They seem developing a new product.

I have a handmade ARMJTAG too which was crafted by a HW technician.
He made one Saturday afternoon looking at Internet resource.  I could
compile a JTAG control program converting from Linux to NetBSD/i386.
Not functionally sophisticated but it's useful enough to break/download/start
any program.  (I love a simple cmdline tool) I used the boilerplate jig extensitvely
to develop LIBSA bootloader code.  Olimex products are compatible with many
sold in market and various IDEs/tools floating around and probably good buys.
