Where can I buy Roma Plastina sculpting clay? What kind should I buy?

I'm getting ready to start sculpting again, and I've heard so much about Roma Plastina here on the RPF, I'd like to try it. I've done a search online, but I'd like to know where you other members buy yours from? And I think there's different hardnesses, so which grade is the best to do 1:1 lifesize sculpts with?

Thanks in advance.

I don't know where you live but if you do a search for "Roma Plastilina" on Google.com you should be able to find something local.

I suggest getting a N.S.P. (Non-Sulphur Plastilina) Roma Plastilina and try a Medium Grade or medium Hardness, then cut a brick of Clay
into small slices like cheese and then mash-up the Clay in your hands to work it and make it softer.

Also the grade of Clay that is best for Sculpting with is a matter of preference, it depends on you, I've used all kinds depending on the project.

I buy from http://www.chavant.com, and http://www.Lagunaclay.com, there are also many local Art Supply stores tha carry Roma Plastilina.
