Jim, I have built a couple of these fiqures and found them to be good, they are, as neudog said, a good point of entry into fiqure modelling. This due to their lower cost and ease of build compared to resin fiqures.
Tamyia acrylics can be very hard to handbrush on to fiqures and usually requires a lot of practice to develop the require techniques, I mainly used Humbrol enamels and oils in the past but now use Vallejo acrylics.
