I like the fact that some fixtures have loads of control features. For me, I'm not to the point where it makes sense for me to buy fixtures that have that much control. Not saying all this control isn't great. The better designers can really utilize that type of control as they see fit.
One thing I'd strongly advise is that if you are planning to buy a controller, don't think "now" unless you know for a fact that "this is all you're gonna get". If you don't plan ahead, then you may find out that you've spent afair amount of money on what may be good hardware, but isn't going to grow with you. This makes it more of a "bad investment", requiring it to be replaced sooner rather than later. What that pain threshhold is varies from user to user.
In my case, after over 7 years now of ownership, I still haven't outgrown my DMX Operator, which is a fairly simple and easy to use controller. It can control a total of 192 DMX channels. It's been a great reliable workhorse bit of gear for me and has served me well, and with a little care, it should continue to serve me well. Even so, it has limitations when it comes to scene programming, taking into consideration what type of lights and the variety of lights I have. So, I've moved towards MyDMX and have been pleased.
I don't think the DMX Operator would be ideal for your 29 channels of DMX control. Maybe for 11 channels or maybe 13, but not 29!
Just make sure you plan a few steps ahead. Throw out of the picture "it ain't fitting in a rack" or lack of rack space. I almost always have surfaces available, generally on top of racks, to put "oversized gear". In my case, my MacBook Pro running Bootcamp for MyDMX(and sometimes ProTools) goes on top of racks at events. Since you're gonna have to plug in a DMX cable into the rack anyways, what difference does it make where the controller is, right?
If anything, hold off and do more controller eval, make some calls, see if you can get some loaner units. Regardless what you do end up going with, just try to see yourself getting 5+ years out of it. Hopefuly. Maybe things explode and you end up going big fast. Who knows. That would be a good thing.
