serp, I'm an east sider, Cleveland Heights. I like the idea of knowing everything that went into my system, as well as how to take it apart and re-build it. And yes, I tried to under-rate my equipment for the exact reason you gave.
When looking at the RK2 and RKE. Here are a couple of thoughts:
1. I don't really know what the Elite can do that the RK2 can't. I read the specs, but the problem is that I've never implemented either, so telling me that is has more channels (for example) does not translate into anything "real" for me. I don't know how I would/could utilize that to my advantage.
2. I don't know when the RKE is coming out, and someone mentioned that if I wait to get either controller, I will pretty much pay for the items needed to set my system up now (timers, powerstrips, etc) then have to pay again for the controller. When I might be better off just paying once upfront. Not knowing the release of the RKE makes it more likely that I would just buy a RK2. As you said, I can always upgrade. (especially if once I start I can understand and appreciate the added functionality).
So what would the RKE give you over the RK2. What would make you upgrade?
