And the price is listed as $329 which with the $149 for the wiggler cable makes it a tad expensive. Ian
What microcontroller to buy?

I very much would not recommend using any 8051 variant, considering what is now available. Those are very inefficient processors that offer nothing other than their ubiquity. The MSP suggested below is a good choice for low power apps, but runs at only 8Mhz (16MHz for a few).

Also, you'll find SPI _and_ UART are sparse/non existant on the smaller MSP430's -jg

It is not inefficient - it has many bit level instructions ideal for embedded applications and the fastest variants are capable of 100 MIPS. Ian
