£150 is certainly steep, and I also do't like the skulls (although you can always stick a hill/other terrain on it). Apart from that, I am minded to stick to their new cloth (at around £15-20), and some hills.
Overall, much more flexible, takes up even less space and I don't need to paint it (always a bonus). If I am looking for desert look, I can always spray/dye the cloth.
Kudos to Pureblood on finding the tutorial.
