Not yet but soon.  I just bought a LPC2103 development board from 
Embedded Artists.  That was based on Mike Harrisons mention a few days 
ago.  So far, I have only powered it up to verify that it works - it does.

The package is a 48 LQFP which I find much more accessible than one of 
the QFN's or BGA's that some other vendors use.  It's supposed to do 
somewhere around 60 MIPS of 32 bit instructions and has peripherals 
galore: 2 I2C, 2 UARTS, 2 SSP'S, up to 32 bits of I/O, etc. It looks 
like a PIC on steroids.  And under 3 bucks in 100's...

Mine came from LPCTOOLS.com; there are other vendors as well with 
similar products.
