LPC2124 and ML67Q5003 are almost identical as characteristics and 
peripherials, core clock, temp range etc.

OKI have a number of advantages though:
-OKI can support SDRAM which is big plus for RAM hungry applications
-OKI have double the Flash memory 
-OKI have DMA channel 
-OKI have 8K cache memory (not 128 bit as LPC ;)

We are working on our OKI range of dev boards and they are based on 
ML67Q5003 chip.
The minus? OKI 5003 cost 50% higher than LPC2124, but they have their 
base line too which starts from EUR 4.00 for the flash-less uC

My advise if you can do the job with LPC2124 stay with it. It's more 
easy to obtain. Japanese IC vendors are horrible to work with small 
(under 10000 pcs) quantities ;)
