I too would recommend Campo or Gromley lines over most. I knowD&A-http://dnarabbitry.tripod.comis almost all line based from Campo. They have some awesome stock, andprices are reasonable. They are located in Oklahoma. For Gromley lines,you can try Kim's Rabbit Treehttp://kimsrabbittree.tripod.com.I purchased several rabbits from her. She has great stock also. She islocated in Tennessee.
Hope this helps. And welcome to the wonderful world of hollands.
