well there are lots of other kits out there, if you need help soldering I can help out so don't limit yourself.
I've been using stuff from

Personally I like it better than other alternatives, especially the drivers but they are PWM so you'll need 0-10V interface for APEX, but you can get three drivers that do 7 LEDs a piece so you could potentially have three colors with independent control.
