Geez, I was figuring I would get a lot of superbrights replies, since everyone talks about them. Theoretically speaking I guess that you can go with the brightest you can find that'll fit into a pushbutton body...I mean, you can't really go too bright, can ya?
...oh, and johnnysmitch, that panel's the purdyest darn thing I've seen in a while! I'm assuming those aren't white happs--they look too good...
