i can get neons through a mate of mine, but price depends on size. the biggest is the 1.2Metre (48 inch) neon, that what i use, they fit nicely under a 33, could prob get for around $90-100 each maybe less not sure, which is pretty good, seeing as most stereo shops sell em for $120-130, and then the prices go down from there, depending on size.
colours i think are, blue, red, green, orange, UV (i think), purple, its possible there could be more colours, ill have to do some checking,
Strich9ine: im not sure if white is available in those neons but ill have to check exactly what is. but blue neons on a white 'line look good, the ones i have on mine now were on my last 33 and that was white
