Phil,
There are some threads on these chips on
<http://finance.groups.yahoo.com/group/geckodrive/>. My memory is that
they were not very complimentry. There seem to be better single chip
solutions available such as the ones used by
<http://www.hobbycnc.com/>. As for me, I'll stick with Gecko's. I'm
way more interested in chips and machines than electronics :->
