I'll be playing around with some cheapo XR-E's R2 from dealextreme while I get my feet wet, but after that, I'm at a loss.

I'd like to get something that is easy to work with, easy to find, under $25/chip, easy to get optics.

I'm a bit curious about everyone's feelings on the P7 D-Bin vs. MC-E LED's.

In my final setup, I'd like to be running 2-3 LED's.

What are the good colors for the P7 D-Bin's? I found a deal for SXO - I can get 10 for $15/piece.
