Anyway hopefully somebody finds this useful and please don't be shy to share the guide/blog around. You can find links to most of the manufacturers websites on the lower right hand side bar on this blog which may be of added use. Noteable admission are Blackhat, Hasselfree (same size as Heresy) and White Knight although there is a mini in the last few images.
