hmmm .. sounds fun.  You should sell 1.25 of each at the current rates ;)) .. 
still .. (as they guy who tied helium ballons to a deck chair famously said: 
.. "a guy gant just sit around" ..)

Im also looking at the Gecko2002 .. thats almost *exactly* what I need .. 
except its USB and usb under linux is always a deeply painful experience with 
much pulling of hair and frame overuns etc. .. the advantage is that it ships 
sometime in the next 10 days ...

Right now I'm just scraping around in the bottom of my wallet to see if I can 
find enough to order a stepper board from jon ... hmm .. maybe the kids piggy 
bank .. wheres my hammer? ....
