in our group we spent much time on isolating RNA from kidney beans. Finally, we 
get use of the Qiagen kit, as a previous poster pointed out. Another fine and 
cheaper is method is described by Hall et al. (PNAS 1978 75:31). It is 
especially useful for difficult material like seeds. The only problem we had is 
the final LiCl precipitation, where much salt coprecipatates with the RNA. We 
are gong to replace this step by a commercially available spin column (some 
cheap ones, they are all nearly the same). You can probably make a deal with 
the manufacturor...
Hope that helps,
