Nothing wrong with NastyDollars that I know of. It actually does convert well.
Because of that, some owners push that on their own sites and do not want it to be overwhelming like a nasty dollars LL. Variety is the spice of life
Many submitters use it so the content gets overused alot. I have no problems with it and I would list it unless I have seen that content a bit already. Since your sites look good some owners, including myself, could overlook that part.
