i would personal have a look at firebywire, if you want something that will work as a simple digital system but can be upgraded to work as a full computer controlled system firebywire is the one. the smallest system is 64 cues and they will even supply the wiring diagrams so you can build your own slat boxes, cables ect to go with it (if you want) will cost around £750 but you can buy more cues later and add them to your existing system.
when i looked at the other firing systems like fireone ect i found them to be old, out-dated, and way more expensive, and firebywire is uk based.
have a look http://www.firebywire.co.uk/
Thanx allot for your help I have e-mailed MLE regarding this system. I agree all these other firing systems seem well overpriced!!
speak soon
