that's not true... you could always just make your own...

well, maybe a DiY option isn't the best choice for you then :-)
have you considered using a PLC?
PLC's have a certain amount of 'smarts' built into to them, so they can run semi autonomously giving you the most robust solution possible, ie even if your master control server/PC crashes and burns as PC's (or in my case Hard drives/SSD's) occasionally tend to do, whatever you have hooked up to the PLC will still have at least basic functionality...
the
Koyo Click PLC is a pretty good value... starting at $70
and
CQC already has a driver for it...
or another option is Weedtech (I just like their name...)... they have a
couple different output modules
no current drivers for any of their stuff, but not to hard to make your own... I have their I/O module, works well...
although, it still hard to beat the over all value of the Koyo...
of course, at this point I would personally still just do something 100% DiY, just for fun... all it would take is a PIC (or arduino if you are into that sort of thing) and a bunch of relays...
NOTE: As one wise professional something once stated, I am ignorant & childish, with a mindset comparable to 9/11 troofers and wackjob conspiracy theorists. so don't take anything I say as advice...
