I'v posted up a little review of the routout drivers as i have used them for my first machine, a mate of mine is also using them as we speak. I cant see any problems with them, other then what kip said about the driver chips used on the routout drivers.

The driver chip used shouldnt be a problem if you get everything wired up right, i did blow one of mine tho so it can be done. The DIYCNC drivers sell quite well and they are cheap to and you get good support from Roy, they use the Allegro chip you can get them from places like RS and a few others so not to bad if they do go pop but again its going to be down to user error i think.

Other then that the MSD range of drivers from Zapp Automation or myself or even MCP would be a good chice, the MSD range do cost a little more but they are VERY nice drivers and if you go for anything above the MSD542's they come with build in fuse's as well.

Routoutcnc driver says good bye

Another note on the DIYCNC drivers would be that you cang et those as a kit with the driver chip already on the cards so that brings the cost down as well.
