I rate the Old Crow models very highly. They are the cleanest, crispest resin models I have ever assembled. They scale a bit smaller than WH40K, though - but are great for any 25mm or realistic scaled 28mm minis.
I couldn't agree more "Target on my back" by far the best cast resin i've ever worked. And i love the simplicity of the designs too with the notched plate look holding the whole 'family' of vehicles together.
