when things come from china, i wouldn't be surprised if you order the exact same thing, it would show up assembled in a different way.
it seems like rgb is all the rage now, so just make one pcb, and if someone wants just red, then change the leds and resistors and keep the pcb since that would be the hardest thing to come up with out of all the components.
Steve, a lot of single color led's now come in 4 or 6 pin packages. in some cases, they're all bound together, and in some cases, it's just 3 seperate leds all the same color. whites seem to always have that "reflector" in them that are yellow. That's what tipped me off.
