I'll get the brand my dad installed at my sisters. Was around $2.80 sqft not installed if I recall and that was middle of the road variety. VERY nice stuff! Look like just cut lawn 365. They have dogs so about once a month he hoses it down with vinegar to help with the pee smell.
Also, when installing you are supposed to add a very thin layer of sand rubber on top that works its way into the grass and keeps it upright.
edit:
like mentioned above. there is the good stuff and the already cut rolls Costco sells. You want the kind that has a thick base to it. The varieties my sister showed mean when she was choosing all looked amazing. Her's looks perfect a year after its been installed.
.. and the brand?
