Monolith
plenty of terrain, historical and Sci -fi also sells the Jim Bowen 40mm range of figures http://www.monolithdesigns.co.uk/

Nice minis , although I find them a little too "cartoon" like for my taste. I was looking at 1:48 horror and really like the Dead Reckoning series by HLBSco http://www.hlbs.co.uk/series.php?id=37 PM
