Yes, they have been around for a long long time. People have used their grunge with good results. Their customer service does leave something to be desired, as it's very hard to get them on the phone. I know sometime ago a couple of their main people were sick and out for a while, so I'm not sure who is running the place anymore.
I have order stuff from them, especially the grunge and some live rocks. I believe one of the main partner passed away leaving the other partner alone to run it, so the site is a messed put is still useable.
