I recently put together a 2A kit. First let me say that it is very well
done and works well.

I keep hearing people trivialize the amount of time that it takes to
put together -- don't be fooled: there are a lot of parts, the pins
are close together, and unless you do this sort of thing for a
living, it can take some time to put together right.

One MINOR nit is that the instructions in the kit only help you put
it together (just look at how many posts there on this board about
power supplies, wiring motors, etc). This took me some
additional time, once again because I was trying to save money,
when I wired up my "salvage" motors. Even using the
"suggested" test software took some time to configure properly.

Finally, this is no speed deamon. I can only get about 1000
steps / second before I start loosing steps. This translates to a
little over 7 IPM of motion.

My conclusion: unless you are REALLY hard on cash, and are
not REALLY sure this CNC stuff is for you, go for the assembled
stuff. This goes double if you aren't that slick with a soldering
iron.
