Hi,

I am writing this e-mail on a Laptop that does not have a parallel
interface. The Keil U-Link has a USB to JTAG converter, the Olimex
connects to the parallel interface.  There are many so called
"wigglers" out there connecting to the parallel port, there is much
more soft- and hardware development required to generate a USB to JTAG
device like the U-Link (or the J-Link for that matter).

As for the Olimex board, it has been around for a while and seems to
be fairly stable. 
Other boards you can look at are the
http://www.embeddedartists.com
or http://www.newmicros.com 
The shipping can already become a significant part of te purchasing
price depending where you are located ;-)

by the way, if you want to use the Rowley tools, you want to use a
wiggler because the USB to JTAG are more specific to the tools of the
manufacturer, U-Link goes with Keil, J-Link with IAR.
