Best plant RNA kit?

I was wondering if I could get a few suggestions about which
RNA extraction kit to use for plant tissue?  My species is a
small, non-woody weed (sort of like Arabidopsis in consistency
actually!).  I've been using Ambion's RNAqueous-midi kit (with
homogenization by grinding in liquid N2 followed by Dounce) but
yields have been downright pathetic (<100 ug per g of tissue)!
I've heard that RNEasy from Qiagen is good.  Any advice would be
greatly appreciated.
