I've got a couple sideshow items, and three bowen busts: punisher, quicksilver and the goon. Those are just awesome, very high quality busts. The nice thing about these is that you can buy one of them and not having to shell out an enormous amount of money. For an awesome sideshow piece you'll have to, since they almost have no cheaper pieces. Of course, you will have a piece that's a lot bigger, but if you want a nice mini bust for say 50 bucks so you can also eat decent, you'll have to go bowen.
However, sideshows quality in statues is very, very good, and some of the materials like real metal are also very cool; and Bowen doesn't do this. What I like a lot about bowen are the museum posed statues, which sideshow doesn't really have. Anyways, it is easier to build a big collection of bowen pieces since overall they are quite a bit cheaper. But look at sideshows Doom PF: Bowen will never, ever produce something as superb as that, and you all know that's true.
