Hey, I have recently been introduced to a new basing company. These guys make some pretty awesome tuffs. They even have varying density and wide range of color selections for the standard grasses. What is super awesome are their moss patches and flowering or thorny tuffs. Check them out: http://www.gamersgrass.com/ I am looking forward to pick up some their tuffs soon.
I probably only use them for the Tufts, which look immensely affordable. Depends on shipping though of course
