Leonard Ornstein <lenornst at pipeline.com> mentioned the
colorless cryptomonad Chilomonas paramecium.

there are numerous other leucoplastic protists, scattered
among the euglenoids (e.g. Astasia), green plants (e.g.
Polytoma, Polytomella, Prototheca), stramenopiles (e.g.
Paraphysomonas) and red algae (the various parasitic 
species).

some papers that might be of interest; abstracts
available on Medline, accessible using NCBI's Entrez 
browser (http://www3.ncbi.nlm.nih.gov/Entrez/):

Gockel, 1994 
     Genes for components of the chloroplast translational
     apparatus are conserved in the reduced 73-kb plastid DNA
     of the nonphotosynthetic euglenoid flagellate Astasia longa. 
     Curr Genet 26, 256-262 (1994) [95163124]

Gaffal, 1980 
     Morphogenesis of the plastidome and the flagellar
     apparatus during the vegetative life cycle of the colourless
     phytoflagellate Polytoma papillatum. 
     Cytobios 27, 43-61 (1980) [81023396]

Goff LJ, Coleman AW.  1995.  The fate of parasite and host organelle
     DNA during cellular transformation of red algae by their parasites.
     Plant Cell 7: 1899-1911.  [not in Medline]

hope this helps.
