To Dan, no I don't know the 15mm range you'Ve linked. However the figures do look good, I would probably go for 28mm though as most of my vehicles and such are to a broad 28mm standard.
To Hang Tuah, I assume as much, I have yet to grab a Helion book, I have a few wishlisted as they seem to be promising reads, albeit with potential risk of motivating the pile of shame to grow in size and unpainted lead.
