As a cheap starting point you could wire up a DIP8 socket and a PLCC32
socket to a Minimus USB (Atmega32U2) device. Those things are available
for ~12 USD, and they have enough GPIOs to drive LPC/FWH/SPI with ease,
and they speak native USB instead of USB-serial emulation. There's even
some code available for LPC/SPI on Atmega processors (originally written
for serprog usage) and you could reuse that easily.
IMHO that would qualify as cheap and readily available. You have to
solder the sockets and write the code yourself, though.
