please recommend me a RNA isolation kit - RNA isolation from 100 tumor cells (Dec/01/2004 )

hi, everybody,
would you please recommend me an excellent kit for isolating RNA from 100 tumor cells? i used RNAeasy kit( QIAGEN) but the RNA recovery is very low. your advice will be appreciated.

Keep in mind that 100 cells are quite few... QIAGEN also has a MIcro version for RNA isolation kit...
