Hi i looked into these a while ago, they are quite pricey but the reviews do seem very positive(i spent hours looking for all sorts) They do say they have an initial start up package but i found they would pretty much bend over backwards to try and sort the right package for you. Unfortunately I hadnt got the available cash flow to take it on, and in hind sight im not sure that my clients would pay herzog prices. In regard to samples i was told that if i wanted to try any products then the cost of them would be refunded in my set up costs.
Please keep me posted if you do go down this route as i would love to hear some feedback from someone using it from a professional point of view. xx
