Nasdaq 100 components?

[Sven Napolean Montessori <snm@xxxxxxxxxxxxxxx>]

I've been using

http://www.nasdaqtrader.com/dynamic/nasdaq100ndx.stm

to determine the members of the Nasdaq 100 index.  But it is listing 4
symbols that are dead (or near dead): PSFT, VRTS, SPOT, and FHCC.

Does anyone know a better source for the components?  Or what is going
on here?  Or perhaps the most interesting to me, what prices to use
for those symbols in calculating the index?

TIA
