Pixel Blocks - deluxe sets / Artist color packs

I'm looking for complete and in very good condition - either Pixel Blocks Deluxe sets, 2800 pieces, and/or individual packs of specifically the artist or photogray colors of Pixel Blocks (which were available from the manufacturer for a limited time only). I have tons of Rainbow colors of Pixel Blocks, but am wanting to acquire Artist and Photogray colors in addition. They need to be in good condition - unnicked, etc. so they can be assembled and generally unscratched so they retain clarity.
