And if you buy the power supply from Happ, be aware that they've had some problems with the leads being put together backwards on a few of them when they are made (in Taiwan, or wherever). I got one of these - drove me crazy til I figured it out!! The interface & optic boards are diode protected, so it's doubtful you'll hurt 'em hooking it up wrong - until I found the problem I did, a lot! :-)
