Monster Makers clay is defiantly worth the extra money. I have made my best sculpts using his clay. I have sculpted from Roma to chavant nsp and finally to monster clay and Arnold goldmans formula wins hands down. I honestly wish I used his clay from the beginning. The last I knew he had some samples available give them a call and see if you can get a sample from him. Plus his book is also very helpful on the subject. Id order the book and see about the sample from him to see if you like it.
