Catlin, for tiling give Tesselation a whirl, it' sonly 15 bucks at the Flaming Pear Website. Those are the only filter's I've ever shelled out for brand-new (I scored my KPT at Half-Price Books!!!!) But most of them are REALLY cool. Tesselation will help you make tileable textures from most any image, Although the source resolution needs to be really high.
