Long story short I am working on my first commercial product and the lpc17xx series of cortex-m3 processors fits the bill. Picked up this lpc1788 system on ebay for a whopping $47 + $16 = $63 verses the 399.99 it used to cost new. Board appears to power up - comes with JLINK lite for debugging ... Heres a breakdown and pics
