I've used them, and they are very good, but expensive. Another option would 
be to use a small '2313 AVR (or a PIC) as a software UART connected to the 
LPC2000 via SPI. I did this once for a comms hub, with software SPI running 
on three '2313s, connected to a mid-range PIC, and it worked very well. 
Hardware cost will be lower, but software will have to be written. It was a 
cheaper solution in our case, for quantity production.
