I received my Parallax SX
Tech Pro board today.

It looks like a pretty fun system. I spent about 2 hours on the phone with friend
that bought the same board. We were able to get it hooked up and working. We also
did some back hello world kind of testing. It will take a couple of days of reading
to get a basic feel for programming this little gem.

The SX28 chip is only about $2.50 a piece so a person can actually afford to build
some projects with it.

The images were lifted (screen
captured) from the website in case they disappear over time. They are very nice
references to their very nice product.
