This is all just my opinion but I don't really like the look of the RDL7 stuff. In all the promo's and renders I've ever seen it just looks to darn 'busy'. Stonemason has some really nice stuff, but so far it's most useful for limited run images or in scene filler. Stuff like promo shots or gallery images. The Decotech sets here at rendo are pretty cool builder sets, but they can work best in interior scenes. Davorama's Sci Fi Construction Set at DAZ and his DreadWorks/Ultimate Sci-Fi Settings sets on his www.beyondbent.com site are very useful for comic book style scenes. You can really load them up in a scene and get Poser to render them. I own chunks of most of these sets and I find that mixing and matching is also very useful so as your budget allows build up a nice library of props and figures to set your scenes in and good luck.
