Lpc2000

Hi,

I'm a complete newbie with arm development, previously I've been using
maxim TINI java embedded systems and Micrchop PICs.

I now want to switch to arm and plan to buy the following components:

Olimex LPC-P2148 PROTOTYPE Board
Olimex ARM-JTAG DONGLE
Rowley CrossWorks for Arm 1.5

Is this a good selection to start with?
I want to do usb and mmc card programming as well as interfacing with
sensors and pwm servos.

Btw, why is the Olimex JTAG dongle so cheap and others are extreamly
expensive?
What does the $199 Kail ULINK-LPC2000 JTAG Debugger on www.lpctools.com
better than the Olimex one?

thanks philipp
