Any Clone-A-Willy products that use a better material?

I think this is the coolest idea. and I'd love to try it and be able to have my man 'around' all the time. but the material really concerns me. rubber is just bad all around. and I keep reading really terrible reviews for this. that it's hard to get right and that the material cause irritations, etc. and I'd be too scared to try it for myself because the cost is so steep. does anyone (who knows more about materials) know whether or not it's possible for this kit to even be able to be made of a better material?
